Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100308, here are decompositions:
- 11 + 100297 = 100308
- 17 + 100291 = 100308
- 29 + 100279 = 100308
- 37 + 100271 = 100308
- 41 + 100267 = 100308
- 71 + 100237 = 100308
- 101 + 100207 = 100308
- 139 + 100169 = 100308
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,308 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
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.
