Something odd(max n listed as 199950, not 200000)

Guys, I'm positive I entered 200,000 as the max n when I began sieving, but the sieving program and the generated file both listed the max n as 199950.

If I don't find a prime, or quit early, what should I list as being checked, 200000 or 199950? If I don't get a satisfactory answer, I'll simply assume it's best to post 199950.

Thanks

I guess all n's between 199,950 and 200,000 have been sieved out. There is no need to further sieve in that range. You can report 200k as the upper bound.

That's what I think. Can anyone confirm this theory?
