Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166460, here are decompositions:

3 + 166457 = 166460
31 + 166429 = 166460
43 + 166417 = 166460
61 + 166399 = 166460
67 + 166393 = 166460
97 + 166363 = 166460
103 + 166357 = 166460
109 + 166351 = 166460

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 166,460 and was likely granted around 1874.

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