Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 246, here are decompositions:
- 5 + 241 = 246
- 7 + 239 = 246
- 13 + 233 = 246
- 17 + 229 = 246
- 19 + 227 = 246
- 23 + 223 = 246
- 47 + 199 = 246
- 53 + 193 = 246
Showing the first eight; more decompositions exist.

Most NANP area codes have multiple overlays in dense regions; the primary area listed is the historic/largest population center for this code.
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.
