Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104512, here are decompositions:
- 41 + 104471 = 104512
- 53 + 104459 = 104512
- 113 + 104399 = 104512
- 131 + 104381 = 104512
- 269 + 104243 = 104512
- 281 + 104231 = 104512
- 389 + 104123 = 104512
- 479 + 104033 = 104512
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 104 512 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
