You're on Windows aren't you? I do know you have a far more powerful machine than I do. I'm running Ubuntu with Gnu compiler. (I tried Clang, but it's slower)
I compared your code against mine on a AMD 7950X.
Which operating system, and which compiler?
It's probably also worth trying for a much larger number of primes. I wrote my command line parser so it will try to read the number as a double if it isn't an integer.
For 100000000000 primes my code on my machine is 39s, and yours is 3:46.
(I've got the mod30 version down to 28s now, but met an intractable optimiser funny)
