Here is a frequently asked question at the Prime Pages:
I am working on an algorithm and need a few of the largest primes with 64 bits.  Where can I find them?
To which we answer "here!"  Below, for each consecutive value of n we give the ten least positive integers k such that 2n-k is a prime.  In each case these are proven primes (proven using UBASIC's  APRT-CL). Note that 2n-k will be an n bit number (for these k's).


Pages: 8-100 bits, 101-200 bits, 201-300 bits, 301-400 bits

 
n ten least k's for which 2n-k is prime.
