Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78126, here are decompositions:
- 5 + 78121 = 78126
- 47 + 78079 = 78126
- 67 + 78059 = 78126
- 109 + 78017 = 78126
- 127 + 77999 = 78126
- 149 + 77977 = 78126
- 157 + 77969 = 78126
- 193 + 77933 = 78126
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.
