Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71372, here are decompositions:
- 13 + 71359 = 71372
- 19 + 71353 = 71372
- 31 + 71341 = 71372
- 43 + 71329 = 71372
- 79 + 71293 = 71372
- 109 + 71263 = 71372
- 139 + 71233 = 71372
- 163 + 71209 = 71372
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.22.204.

Unspecified address (0.0.0.0/8) — "this network" placeholder.
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.
