Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180500, here are decompositions:

3 + 180497 = 180500
37 + 180463 = 180500
109 + 180391 = 180500
139 + 180361 = 180500
163 + 180337 = 180500
193 + 180307 = 180500
211 + 180289 = 180500
241 + 180259 = 180500

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 180,500 and was likely granted around 1875.

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