Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136904, here are decompositions:
- 7 + 136897 = 136904
- 43 + 136861 = 136904
- 127 + 136777 = 136904
- 151 + 136753 = 136904
- 193 + 136711 = 136904
- 211 + 136693 = 136904
- 283 + 136621 = 136904
- 331 + 136573 = 136904
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 136,904 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
