Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165850, here are decompositions:

17 + 165833 = 165850
71 + 165779 = 165850
101 + 165749 = 165850
131 + 165719 = 165850
137 + 165713 = 165850
149 + 165701 = 165850
197 + 165653 = 165850
233 + 165617 = 165850

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 165,850 and was likely granted around 1874.

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