Storing very large numbers in Java

I'd like to store a long integer in Java, specifically the 6144-bit MODP Group (Group 17) from RFC 3526. However this number does not seem to fit to a BigInteger. Is there a way to use this prime number in Java?

EDIT: I tried

BigInteger p = new BigInteger(Integer.toString(pValue));
p = 33751521821438561184518523159967412330064897805741846548173890474429429901326672445203235101919165483964194359460994881062089387893762814044257438204432573941083014827006090258925875161018096327732335800595831915976014208822304007327848132734933297885803213675261564962603340457220776826322500058091310967253976619973988033663666385188155212656268079501726223369693427999804134467810120772356498596945532366527400517575471969335854905274504119509592366013711954148258884879224599915203456315881034776553083676995718335598586395591169999570824515035017543533352697525287753332500527176569576894926734950469293596134095086603716860086302051544539652689091299099784588919052383463057789440565460681441902442399956419060521629604697347879024654313800186078316526964529288062740879011035175920059192178561473199006205896719435014765345518490882366607110905303449152556221163232127426440691921134648766635695850239231304591744215610985029636895406718880766308249227315984267542266259489684372223916445411015900506239419267909716320331208988978180868987431623710347617992356201449023892203230133009421463914291201346063125219636964261683591541014344239275340735690997732222069758773963390876360546515755280517042160525487302898122311669799679447530453600399342697032714458549591285939453949034981248114322322367238645042515984447890788917823576330019151696568654314153058547592091366014550143819685170068343700104677609041166369760080933413605498962382077778845599834907475953430787446201384567328530675275792962354883770806900827183685718353469574731680520621944540947734619035177180057973022652571032196598229259194875709994709721793154158686515748507274224181316948797104601068212015232921691482496346854413698719750190601102705274481050543239815130686073601076304512284549218459846046082253596762433827419060089029417044871218316020923109988915707117567;

Use the BigInteger(String val) constructor to create the number, that is: pass the number as a String. The BigInteger class implements an arbitrary-precision integer data type, any integer can fit - as long as there's enough physical memory to represent it:

BigInteger p = new BigInteger("33751521821438561184518523159967412330064897805741846548173890474429429901326672445203235101919165483964194359460994881062089387893762814044257438204432573941083014827006090258925875161018096327732335800595831915976014208822304007327848132734933297885803213675261564962603340457220776826322500058091310967253976619973988033663666385188155212656268079501726223369693427999804134467810120772356498596945532366527400517575471969335854905274504119509592366013711954148258884879224599915203456315881034776553083676995718335598586395591169999570824515035017543533352697525287753332500527176569576894926734950469293596134095086603716860086302051544539652689091299099784588919052383463057789440565460681441902442399956419060521629604697347879024654313800186078316526964529288062740879011035175920059192178561473199006205896719435014765345518490882366607110905303449152556221163232127426440691921134648766635695850239231304591744215610985029636895406718880766308249227315984267542266259489684372223916445411015900506239419267909716320331208988978180868987431623710347617992356201449023892203230133009421463914291201346063125219636964261683591541014344239275340735690997732222069758773963390876360546515755280517042160525487302898122311669799679447530453600399342697032714458549591285939453949034981248114322322367238645042515984447890788917823576330019151696568654314153058547592091366014550143819685170068343700104677609041166369760080933413605498962382077778845599834907475953430787446201384567328530675275792962354883770806900827183685718353469574731680520621944540947734619035177180057973022652571032196598229259194875709994709721793154158686515748507274224181316948797104601068212015232921691482496346854413698719750190601102705274481050543239815130686073601076304512284549218459846046082253596762433827419060089029417044871218316020923109988915707117567");
