Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105918, here are decompositions:

5 + 105913 = 105918
11 + 105907 = 105918
19 + 105899 = 105918
47 + 105871 = 105918
89 + 105829 = 105918
101 + 105817 = 105918
149 + 105769 = 105918
151 + 105767 = 105918

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 105,918 and was likely granted around 1870.

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