Peter,

Per this post, you had 21 k's remaining at n=50K. The 2 primes here leaves 19 k's remaining at n=100K (vs. 17). Doing a balancing of everything confirms that there were 32 k's remaining at n=5K and 13 k's with a prime for n=5K-100K so indeed there are 19 k's remaining.

You are right of course. I had 19 remaining k's in mind and for some reason subtracted the two newly found ones again. Sorry for the confusion!
