Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55042, here are decompositions:
- 41 + 55001 = 55042
- 59 + 54983 = 55042
- 83 + 54959 = 55042
- 101 + 54941 = 55042
- 173 + 54869 = 55042
- 191 + 54851 = 55042
- 263 + 54779 = 55042
- 269 + 54773 = 55042
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.
