Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66264, here are decompositions:
- 43 + 66221 = 66264
- 73 + 66191 = 66264
- 103 + 66161 = 66264
- 127 + 66137 = 66264
- 157 + 66107 = 66264
- 181 + 66083 = 66264
- 193 + 66071 = 66264
- 197 + 66067 = 66264
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.2.216.

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.
