Get URL (Link) for facebook post using post ID

I am trying to get a post from a company Facebook page.The link is for an application i developed that feeds of information from another applications database that uses the Facebook API.

i want to create a link eg www.facebook.com/{postID} that will take me to the specific post.I have tried numerous articles and all seem to send me to a 404 page. Please help.

Thanks

My Application uses the facebook api that accepts data related to a facebook page content (i.e posts,photo's,statuses etc).part of the api is that it saves the actual post id pertaining to a post for e.g. 302961133120433_576487772434433 into my applications database.As you may see that the post id has 2 parts separated by an underscore.So i needed to make a url based on this post id.

Solution for the link is:(2 parts of it,first being page id and second being actual post id)

Hope this helps.
