Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180850, here are decompositions:

3 + 180847 = 180850
53 + 180797 = 180850
71 + 180779 = 180850
101 + 180749 = 180850
149 + 180701 = 180850
227 + 180623 = 180850
233 + 180617 = 180850
281 + 180569 = 180850

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 180,850 and was likely granted around 1875.

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