Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105866, here are decompositions:

3 + 105863 = 105866
37 + 105829 = 105866
97 + 105769 = 105866
139 + 105727 = 105866
193 + 105673 = 105866
199 + 105667 = 105866
337 + 105529 = 105866
349 + 105517 = 105866

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 105 866 and was likely granted around 1870.

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