Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105912, here are decompositions:

5 + 105907 = 105912
13 + 105899 = 105912
29 + 105883 = 105912
41 + 105871 = 105912
83 + 105829 = 105912
151 + 105761 = 105912
179 + 105733 = 105912
211 + 105701 = 105912

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 105.912 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
