The first 16208 digits of Pi are a probable prime. Ed T. Prothro found this in 2001.

I just finished checking up through 40000 digits. There are no other numbers in this sequence for which Mathematica's PrimeQ[ ] is TRUE.

Has anyone checked beyond this limit?

Could you also try digits of pi to other bases? Particularly base 2. Paul
