Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108812, here are decompositions:
- 13 + 108799 = 108812
- 19 + 108793 = 108812
- 43 + 108769 = 108812
- 61 + 108751 = 108812
- 73 + 108739 = 108812
- 103 + 108709 = 108812
- 163 + 108649 = 108812
- 181 + 108631 = 108812
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 108,812 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
