Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180700, here are decompositions:

53 + 180647 = 180700
71 + 180629 = 180700
83 + 180617 = 180700
131 + 180569 = 180700
137 + 180563 = 180700
167 + 180533 = 180700
197 + 180503 = 180700
227 + 180473 = 180700

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 180,700 and was likely granted around 1875.

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