Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 110, here are decompositions:
- 3 + 107 = 110
- 7 + 103 = 110
- 13 + 97 = 110
- 31 + 79 = 110
- 37 + 73 = 110
- 43 + 67 = 110
As an ASCII codepoint, 110 is n. Printable ASCII character n.
TCP/UDP port 110 is the well-known port for POP3 — Post Office Protocol v3 — mail retrieval.
As an unsigned 32-bit integer, this is the IPv4 address 0.0.0.110.
This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
