Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104720, here are decompositions:
- 3 + 104717 = 104720
- 13 + 104707 = 104720
- 19 + 104701 = 104720
- 37 + 104683 = 104720
- 43 + 104677 = 104720
- 61 + 104659 = 104720
- 97 + 104623 = 104720
- 127 + 104593 = 104720
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 104 720 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
