revive very old post but ...
Pari can be used, just use modular exponentiation using repeated squaring. On my pathetic computer things really slow down beginning at exp=756839. I haven't framed the timing as a f{exp size}. If someone has superior computing capability I would be curious as to their timing for 756839, I can supply the script.
