Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22402, here are decompositions:
- 5 + 22397 = 22402
- 11 + 22391 = 22402
- 53 + 22349 = 22402
- 59 + 22343 = 22402
- 131 + 22271 = 22402
- 173 + 22229 = 22402
- 269 + 22133 = 22402
- 293 + 22109 = 22402
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.
