Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180862, here are decompositions:

83 + 180779 = 180862
89 + 180773 = 180862
113 + 180749 = 180862
131 + 180731 = 180862
233 + 180629 = 180862
239 + 180623 = 180862
293 + 180569 = 180862
359 + 180503 = 180862

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 180,862 and was likely granted around 1875.

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