Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104578, here are decompositions:
- 17 + 104561 = 104578
- 29 + 104549 = 104578
- 41 + 104537 = 104578
- 107 + 104471 = 104578
- 179 + 104399 = 104578
- 197 + 104381 = 104578
- 251 + 104327 = 104578
- 269 + 104309 = 104578
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 104,578 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
