Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171750, here are decompositions:

17 + 171733 = 171750
31 + 171719 = 171750
37 + 171713 = 171750
43 + 171707 = 171750
53 + 171697 = 171750
71 + 171679 = 171750
79 + 171671 = 171750
97 + 171653 = 171750

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 171,750 and was likely granted around 1874.

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