Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105686, here are decompositions:

3 + 105683 = 105686
13 + 105673 = 105686
19 + 105667 = 105686
37 + 105649 = 105686
67 + 105619 = 105686
73 + 105613 = 105686
79 + 105607 = 105686
157 + 105529 = 105686

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 105.686 and was likely granted around 1870.

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