allthatjazmyne, whose math-fu is stronger than mine, noticed that one of the so-called prime numbers I included in yesterday's list was divisible by two and asked, not unreasonably, "How is 4,545,454 a prime number?" Having investigated the matter, I have determined that 4,545,454 is indeed evenly divisible by two and is therefore not prime. I blame the Wikipedia editor at, who on March 3 edited the list of safe primes to include the non-prime. I've fixed the mistake, both on Wikipedia and in my list.
