Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104440, here are decompositions:
- 23 + 104417 = 104440
- 41 + 104399 = 104440
- 47 + 104393 = 104440
- 59 + 104381 = 104440
- 71 + 104369 = 104440
- 113 + 104327 = 104440
- 131 + 104309 = 104440
- 197 + 104243 = 104440
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 104,440 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
