Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108840, here are decompositions:
- 13 + 108827 = 108840
- 19 + 108821 = 108840
- 37 + 108803 = 108840
- 41 + 108799 = 108840
- 47 + 108793 = 108840
- 71 + 108769 = 108840
- 79 + 108761 = 108840
- 89 + 108751 = 108840
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 108,840 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
