Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166860, here are decompositions:

7 + 166853 = 166860
11 + 166849 = 166860
13 + 166847 = 166860
17 + 166843 = 166860
19 + 166841 = 166860
37 + 166823 = 166860
53 + 166807 = 166860
61 + 166799 = 166860

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 166,860 and was likely granted around 1874.

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