Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165150, here are decompositions:

17 + 165133 = 165150
47 + 165103 = 165150
61 + 165089 = 165150
67 + 165083 = 165150
71 + 165079 = 165150
101 + 165049 = 165150
103 + 165047 = 165150
109 + 165041 = 165150

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 165,150 and was likely granted around 1874.

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