Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78948, here are decompositions:
- 7 + 78941 = 78948
- 19 + 78929 = 78948
- 29 + 78919 = 78948
- 47 + 78901 = 78948
- 59 + 78889 = 78948
- 61 + 78887 = 78948
- 71 + 78877 = 78948
- 109 + 78839 = 78948
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.
