Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42246, here are decompositions:
- 7 + 42239 = 42246
- 19 + 42227 = 42246
- 23 + 42223 = 42246
- 37 + 42209 = 42246
- 53 + 42193 = 42246
- 59 + 42187 = 42246
- 67 + 42179 = 42246
- 89 + 42157 = 42246
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.
