4000 < k < 5000
I've decided to start working on the range 4500<k<5000 (sieved to p=3P) with some cores I have available right now.
My plan is to do it in several drives. In the first drive all k's will be searched to n=120k (work in progress). The next drives will extend the range stepwise depending on core availability. All k's have been tested to n=20k, but this range will be DC. Some k's have been tested by others on some higher n's, leaving a gap behind in most cases that is planned to be filled: J.P.Burt k=4515, n=191k284.1k k=4559, n=500k1.0M k=4589, n=500k1.0M k=4601, n=500k1.0M k=4691, n=500k1.0M k=4717, n=500k1.0M C.Chatfield k=4779, n=?? k=4851, n=350k384k RPS 8th drive k=4935, n=380k k=4597 and k=4813 were already searched to n=1.0M (J.P.Burt) with no gaps and initially will be only DC to n=120k. I am on my own in this quest for now, but if anyone wants to join I could post the sieved ranges. Lots of primes are to come!

I've just updated the 40005000 page with the new primes for k=4500  5000, n=20000  200000.
Thanks otutusaus.
