Default P-1 stage 2 factor

I just beat my own personal record and just found a 43 digit factor during stage 2 of p-1 factoring. My previous record was 42 digits.

P-1 found a factor in stage #2, B1=70000, B2=1277500.
UID: dave_0273/buffy, M12215821 has a factor: 2855451057157704997579326497626590663028969

Assuming that I did the calculation correct, this is a 142 bit factor.

I am interested to know if anyone has found a bigger factor using p-1. Also, I was wondering if this number is prime, I highly doubt that it is though.
