Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82442, here are decompositions:
- 103 + 82339 = 82442
- 163 + 82279 = 82442
- 181 + 82261 = 82442
- 211 + 82231 = 82442
- 223 + 82219 = 82442
- 271 + 82171 = 82442
- 313 + 82129 = 82442
- 421 + 82021 = 82442
Showing the first eight; more decompositions exist.

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.
