Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180814, here are decompositions:

3 + 180811 = 180814
17 + 180797 = 180814
41 + 180773 = 180814
83 + 180731 = 180814
113 + 180701 = 180814
167 + 180647 = 180814
191 + 180623 = 180814
197 + 180617 = 180814

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 180,814 and was likely granted around 1875.

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