Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105850, here are decompositions:

83 + 105767 = 105850
89 + 105761 = 105850
149 + 105701 = 105850
167 + 105683 = 105850
197 + 105653 = 105850
293 + 105557 = 105850
317 + 105533 = 105850
347 + 105503 = 105850

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 105,850 and was likely granted around 1870.

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