Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55424, here are decompositions:
- 13 + 55411 = 55424
- 43 + 55381 = 55424
- 73 + 55351 = 55424
- 181 + 55243 = 55424
- 211 + 55213 = 55424
- 223 + 55201 = 55424
- 277 + 55147 = 55424
- 307 + 55117 = 55424
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.0.216.128.

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.
