Did you mean pseudoprimes?

All primes are guaranteed to pass the test. The question is whether there's a pseudoprime that passes the test. Using the same database of pseudoprimes, two independent people have confirmed the 2^64 upper bound. Since that database was the same, it doesn't count as an independent confirmation.
