Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168660, here are decompositions:

17 + 168643 = 168660
29 + 168631 = 168660
31 + 168629 = 168660
43 + 168617 = 168660
59 + 168601 = 168660
61 + 168599 = 168660
101 + 168559 = 168660
127 + 168533 = 168660

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 168,660 and was likely granted around 1874.

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