This is likely the longest currently running n-range without a prime for k<300.

I'm taking k=7 from n=5M to n=8M. Already found a hit.

k=21 is complete to n=3.5M; 1 prime found for n=2.89M-3.5M.

k=21 double-check is complete for n=1M-2.89M; 5 primes confirmed.

The k is released. Primes and results attached.

k=83 at n=3.6M and continuing
