Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105518, here are decompositions:

19 + 105499 = 105518
139 + 105379 = 105518
151 + 105367 = 105518
157 + 105361 = 105518
181 + 105337 = 105518
199 + 105319 = 105518
241 + 105277 = 105518
307 + 105211 = 105518

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 105.518 and was likely granted around 1870.

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