Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104520, here are decompositions:
- 7 + 104513 = 104520
- 29 + 104491 = 104520
- 41 + 104479 = 104520
- 47 + 104473 = 104520
- 61 + 104459 = 104520
- 103 + 104417 = 104520
- 127 + 104393 = 104520
- 137 + 104383 = 104520
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 104,520 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
