Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166510, here are decompositions:

23 + 166487 = 166510
53 + 166457 = 166510
101 + 166409 = 166510
107 + 166403 = 166510
191 + 166319 = 166510
251 + 166259 = 166510
263 + 166247 = 166510
353 + 166157 = 166510

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 166,510 and was likely granted around 1874.

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