[math-fun] Primes in First N Digits of Pi

These are prime: 3 31 314159 31415926535897932384626433832795028841 (first 38 digits of Pi). 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? Bob Baillie
