I can prove that the number to required to sieve to assure only untouchables for the interval 1:N is less than (N/2 - 1)^2,
I can prove that the number to required to sieve to assure only untouchables for the interval 1:N is less than (N/2 - 1)^2 for larger N,
but the 512,000,000 sieved below is just from doubling 1,000,000 and running the sieve until we get 150232 for the number
