Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104240, here are decompositions:
- 7 + 104233 = 104240
- 61 + 104179 = 104240
- 67 + 104173 = 104240
- 79 + 104161 = 104240
- 127 + 104113 = 104240
- 151 + 104089 = 104240
- 181 + 104059 = 104240
- 193 + 104047 = 104240
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 104,240 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
