Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104688, here are decompositions:
- 5 + 104683 = 104688
- 7 + 104681 = 104688
- 11 + 104677 = 104688
- 29 + 104659 = 104688
- 37 + 104651 = 104688
- 109 + 104579 = 104688
- 127 + 104561 = 104688
- 137 + 104551 = 104688
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 104 688 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
