Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54742, here are decompositions:
- 29 + 54713 = 54742
- 113 + 54629 = 54742
- 179 + 54563 = 54742
- 239 + 54503 = 54742
- 293 + 54449 = 54742
- 419 + 54323 = 54742
- 431 + 54311 = 54742
- 449 + 54293 = 54742
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.
