Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105880, here are decompositions:

17 + 105863 = 105880
113 + 105767 = 105880
179 + 105701 = 105880
197 + 105683 = 105880
227 + 105653 = 105880
317 + 105563 = 105880
347 + 105533 = 105880
353 + 105527 = 105880

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 105.880 and was likely granted around 1870.

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