Goldbach decomposition

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.

Possible US patent number

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.
