Default 62-digit prime factor of a Mersenne number

Playing with my applet, i found out this beautiful result:

M1000000000000000000000000000000000000000000000000000000001059 has a factor: 40000000000000000000000000000000000000000000000000000000042361

The factor being a 62-digit prime (about 204.62 bit) obtained with trial-factoring software.

Geee, it's fun!
