Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105812, here are decompositions:
- 43 + 105769 = 105812
- 61 + 105751 = 105812
- 79 + 105733 = 105812
- 139 + 105673 = 105812
- 163 + 105649 = 105812
- 193 + 105619 = 105812
- 199 + 105613 = 105812
- 211 + 105601 = 105812
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 105.812 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
