Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167800, here are decompositions:

23 + 167777 = 167800
29 + 167771 = 167800
41 + 167759 = 167800
53 + 167747 = 167800
71 + 167729 = 167800
89 + 167711 = 167800
137 + 167663 = 167800
167 + 167633 = 167800

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 167,800 and was likely granted around 1874.

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