Hi,

Running the "prp -m" command in the latest development version of

OpenPFGW on around a PIII 933Mhz shows 5 days for 4194304 and 24 days

for 8388608. Your number is in between there. Plus, if you have an

Athlon or Pentium IV, it would be faster. I would say go ahead and

run a PRP test through OpenPFGW, and let us know if it is indeed a

probable prime. It would lend more credibility to your conjecture.

I would try to get a special version of OpenPFGW that will save your

progress every so often so you don't lose your work. Best wishes.
