Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165104, here are decompositions:
- 67 + 165037 = 165104
- 103 + 165001 = 165104
- 151 + 164953 = 165104
- 193 + 164911 = 165104
- 211 + 164893 = 165104
- 223 + 164881 = 165104
- 283 + 164821 = 165104
- 337 + 164767 = 165104
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 165,104 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
