No, I didn't forget it. I'm just holding off on checking it for twins since all of my computing power is currently devoted to the rally

10641*2^482399-1 is prime! Time : 0.0 sec.

Doublecheck (done on a different computer than the one that found the prime):
10641*2^482399-1 is prime! Time : 421.080 sec.

10641*2^482399+1 is not prime. Proth RES64: 5782B69ECBADD215 Time : 426.889 sec.

Quite interestingly, it seems that Mini-Geek has also found a prime on this exact same n...
