Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100104, here are decompositions:
- 47 + 100057 = 100104
- 61 + 100043 = 100104
- 101 + 100003 = 100104
- 113 + 99991 = 100104
- 181 + 99923 = 100104
- 197 + 99907 = 100104
- 223 + 99881 = 100104
- 227 + 99877 = 100104
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 100,104 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.
