Thanks for the link!

Anyway I wrote "and it is not derived from a power of two, like the Marsenne primes", exactly because many large numbers, that have a large integer part, that I saw are power of two with some (relatively small) additions or subtractions.

Take 5 result to compute:
\[ 2^{65536} - 3 \]
