Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42424, here are decompositions:
- 17 + 42407 = 42424
- 101 + 42323 = 42424
- 131 + 42293 = 42424
- 167 + 42257 = 42424
- 197 + 42227 = 42424
- 227 + 42197 = 42424
- 293 + 42131 = 42424
- 353 + 42071 = 42424
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.
