TITLE: What are some easy-to-remember prime numbers?
QUESTION [13 upvotes]: This is a question without much mathematical value, but since I don't immediately see an answer on Google I thought I'd ask anyway ... I'm looking for some largeish (> 10,000) easy-to-remember primes, like palindromes (313), numbers with decreasing digits 54321 (not a prime), etc. The primary purpose is for computer programs, where they are useful for hashing and the like.
What's your favorite, if you know any?
