VBCurtis is correct, GNFS would be pretty quick. You're almost there with the sqrt.

You can run the sqrt in parallel if you have idle cores. Something like:
Code:
./msieve -nc3 11,13
./msieve -nc3 14,16
./msieve -nc3 17,19
...
You might want to use a different folder for each or point them to a different log file so you won't intersperse the output of each run.
