Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173200, here are decompositions:

11 + 173189 = 173200
17 + 173183 = 173200
23 + 173177 = 173200
59 + 173141 = 173200
101 + 173099 = 173200
113 + 173087 = 173200
179 + 173021 = 173200
227 + 172973 = 173200

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 173,200 and was likely granted around 1874.

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