Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180184, here are decompositions:

3 + 180181 = 180184
5 + 180179 = 180184
23 + 180161 = 180184
47 + 180137 = 180184
107 + 180077 = 180184
113 + 180071 = 180184
131 + 180053 = 180184
227 + 179957 = 180184

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 180,184 and was likely granted around 1875.

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