Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172150, here are decompositions:

3 + 172147 = 172150
23 + 172127 = 172150
53 + 172097 = 172150
71 + 172079 = 172150
101 + 172049 = 172150
149 + 172001 = 172150
227 + 171923 = 172150
233 + 171917 = 172150

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 172,150 and was likely granted around 1874.

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