Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168006, here are decompositions:

19 + 167987 = 168006
53 + 167953 = 168006
89 + 167917 = 168006
107 + 167899 = 168006
127 + 167879 = 168006
197 + 167809 = 168006
227 + 167779 = 168006
229 + 167777 = 168006

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 168,006 and was likely granted around 1874.

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