Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104840, here are decompositions:
- 13 + 104827 = 104840
- 37 + 104803 = 104840
- 61 + 104779 = 104840
- 67 + 104773 = 104840
- 79 + 104761 = 104840
- 97 + 104743 = 104840
- 139 + 104701 = 104840
- 157 + 104683 = 104840
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 104,840 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
