I get htis feeling of 'going to take forever' to find the twin.

Again, I'd like to see a much larger prime, but with a lower n value, we could do a lot of work in less time to check feasablity for going higher.

I've posted a sieve file for you since you were interested in doing a multiple n, small k range. It tests n=197000-197009 from k=1-1M. It should be slightly faster to test than n=195000 because of the small k's.

The sieve file hasn't been sieved deeply (only to p=250G) because each n must be sieved separately and because the k range is so small. At p=250G, 1 k is eliminated every 30-40 seconds, while it takes slightly less than a minute to LLR them.

This search for twins a bit above n=195000 might be adapted to Primegrid, but I'll wait until n=333333 is done first.
Note: The file now excludes all k below 124,000 since Flatlander LLR'ed it already.
