Looks like you have to set nmax. With the addition of the "-N 480003" switch, I get:

1022928217 | 14319*2^480003-1
1164933401 | 94509*2^480001+1
1231256737 | 18459*2^480001+1
1243389379 | 67749*2^480003-1
1303197491 | 36513*2^480002-1
1366054969 | 16761*2^480003+1
1482274247 | 59925*2^480001-1
1521564647 | 9225*2^480002+1
1642908313 | 98331*2^480003+1

Edit: Also, MooooMoo, if anyone's planning on using a version with my Montgomery code, a low N=483328 would be more efficient, bit-wise. The high end doesn't matter.

For now, I'll only say that the twin prime is 100355 digits long and has a k value between 65G and 67G.

Thanks for the info. After a day of sieving and testing on 10 quads, I found it and will report it as my own!

You should have used that computing power to contribute to this effort instead:
