Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108820, here are decompositions:
- 17 + 108803 = 108820
- 29 + 108791 = 108820
- 59 + 108761 = 108820
- 113 + 108707 = 108820
- 233 + 108587 = 108820
- 263 + 108557 = 108820
- 317 + 108503 = 108820
- 359 + 108461 = 108820
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 108,820 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
