Yep.
1673*2^352222-1 is prime.
Nobody make any sudden movements or it will fall off the list.

1923*2^352462-1 is prime

Are we having fun yet?

I like the top-5000 score of these primes. This is the first one of the 3 in the new drive that scored > 1.01. lmao

A remarkable pair only n=58 apart for k=1643:

1643*2^352664-1 is prime


352K-353K is a highly prolific range. After 350K-351K had no primes even for the larger k=1005-2000 range, we've already 8 primes for 352K-353K (including prior known) for k=1400-2000 and there's still quite a bit to go.
