Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171500, here are decompositions:

19 + 171481 = 171500
31 + 171469 = 171500
61 + 171439 = 171500
73 + 171427 = 171500
97 + 171403 = 171500
229 + 171271 = 171500
331 + 171169 = 171500
337 + 171163 = 171500

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 171,500 and was likely granted around 1874.

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