Reserving k=607
 

Hey. I did not find any thread which worked on k=607, so I'm posting to tell I'm gonna do work on that starting from 2M :)

I would suggest a visit to the link below:

Thanks! They seem to be doing lower n so I'll update my work to them at some points if they move to 2M at some point :)

2.3% of range checked, no primes yet.

Tested up to n=2025545 now.

Gonna switch to a sieving project so I'm gonna take a hiatus on this. When I return, I'll probably try to run 2-4 instances to increase the speed.
