Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100904, here are decompositions:
- 103 + 100801 = 100904
- 157 + 100747 = 100904
- 163 + 100741 = 100904
- 211 + 100693 = 100904
- 283 + 100621 = 100904
- 313 + 100591 = 100904
- 367 + 100537 = 100904
- 421 + 100483 = 100904
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 100,904 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
