Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168810, here are decompositions:

7 + 168803 = 168810
29 + 168781 = 168810
41 + 168769 = 168810
67 + 168743 = 168810
73 + 168737 = 168810
79 + 168731 = 168810
97 + 168713 = 168810
113 + 168697 = 168810

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 168,810 and was likely granted around 1874.

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