Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180174, here are decompositions:

13 + 180161 = 180174
37 + 180137 = 180174
97 + 180077 = 180174
101 + 180073 = 180174
103 + 180071 = 180174
131 + 180043 = 180174
151 + 180023 = 180174
167 + 180007 = 180174

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 180,174 and was likely granted around 1875.

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