Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185500, here are decompositions:

17 + 185483 = 185500
23 + 185477 = 185500
59 + 185441 = 185500
71 + 185429 = 185500
131 + 185369 = 185500
137 + 185363 = 185500
173 + 185327 = 185500
191 + 185309 = 185500

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 185,500 and was likely granted around 1875.

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