Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105816, here are decompositions:

47 + 105769 = 105816
83 + 105733 = 105816
89 + 105727 = 105816
149 + 105667 = 105816
163 + 105653 = 105816
167 + 105649 = 105816
197 + 105619 = 105816
283 + 105533 = 105816

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 105.816 and was likely granted around 1870.

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