Found single prime: k= 113040057

It seems to me that (in our first results) that there is 1 prime every 8-9 M rather than every 4-5M. Do you agree ? This change the probability of finding a twin ?

[QUOTE=pacionet]It seems to me that (in our first results) that there is 1 prime every 8-9 M rather than every 4-5M. Do you agree ? This change the probability of finding a twin ?[/QUOTE]
I think the average prime density is still 1 prime every 4-5M. So far, there have been 17 primes discovered, and a total of 76M has been marked as complete. 76/17 = 4.47M per prime, which is about right.

We may have reserved all ranges less than 200M, but many of them are still in progress, meaning more primes may be found.
