Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168104, here are decompositions:

37 + 168067 = 168104
61 + 168043 = 168104
67 + 168037 = 168104
151 + 167953 = 168104
193 + 167911 = 168104
241 + 167863 = 168104
421 + 167683 = 168104
463 + 167641 = 168104

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 168,104 and was likely granted around 1874.

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