The first (nonmerseinne) 10 milliondigit prime number!!!
If this qualifies for the contest for $100,000, then let GIMPS do with the money as they see fit.
Since by adding 1 to N! gives a prime number (N! + 1 cannot be factored by any number =<N), this is a simple matter of finding a factorial which has 10 million digits  the first of which being 1,737,441. This gives a prime of 10 million and 1 (I think) digits, with the last digit a 1. (Still computing the value, could take a couple of months :().
1,737,411!+1 = xxx...xx 1.
If, however, you need a Merseinne prime, then I have none.
Good luck in the search!!!
