Manned mission to Mars is order 10 trillion dollar - except if you want to 'throw away the people' with certainty. In short if you do not care they get killed with 99.99% certainty very quickly...

Congrats on that one!
Way further away than i had guessed!!
It had so many primes below 3.14M.
If we do math from there then it's 6.8M which is factor 2 and 11+M is really far away again....

You can be sure i will report it if there is a new one above n=1569 :)

Given: k * 2^n - 1
The risk you run with low-weights is that you do not find a prime at all,
because when the number of bits of the exponent n increases, the testing time goes exponentially up...

Too bad you didn't find anything k=89 * 2^n - 1 until 4M.
Taking over k=89 then. will search it then from 4M to 6M (or maybe 7M) and then release it again probably will let you know when i release...
