Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185200, here are decompositions:

11 + 185189 = 185200
17 + 185183 = 185200
23 + 185177 = 185200
47 + 185153 = 185200
101 + 185099 = 185200
131 + 185069 = 185200
137 + 185063 = 185200
149 + 185051 = 185200

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 185,200 and was likely granted around 1875.

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