What are some easy-to-remember prime numbers? [closed]

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?

My personal favorite prime number is Belphegor's prime: $$1\underbrace{0000000000000}_{13}666\underbrace{0000000000000}_{13}1.$$ In addition to being palindromic, it has $31$ digits which is of course $13$ backwards.

Wikipedia's list of prime numbers includes "palindromic primes"

2, 3, 5, 7, 11, 101, 131, 151, 181, 191, 313, 353, 373, 383, 727, 757, 787, 797, 919, 929, 10301, 10501, 10601, 11311, 11411, 12421, 12721, 12821, 13331, 13831, 13931, 14341, 14741

and "palindromic wing primes"

101, 131, 151, 181, 191, 313, 353, 373, 383, 727, 757, 787, 797, 919, 929, 11311, 11411, 33533, 77377, 77477, 77977, 1114111, 1117111, 3331333, 3337333, 7772777, 7774777, 7778777, 111181111, 111191111, 777767777, 77777677777, 99999199999.
