Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188500, here are decompositions:

17 + 188483 = 188500
41 + 188459 = 188500
83 + 188417 = 188500
131 + 188369 = 188500
149 + 188351 = 188500
167 + 188333 = 188500
197 + 188303 = 188500
227 + 188273 = 188500

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 188,500 and was likely granted around 1875.

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