I think k=17002000 is a nearly barren range! For n=350K to the current processing limit, we have:
23 total primes for k=14001700
3 total primes for k=17002000
This includes confirmed primes so is not biased by previous searching in any way.
As Chris is fond of me saying: Primes are very strange!

There's
very strange and then there's
really weird.
This sort of thing used to drive me nuts when I would do (semi)fixed n tests. Five primes for one n, then none for the next etc.
