Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188600, here are decompositions:

37 + 188563 = 188600
67 + 188533 = 188600
73 + 188527 = 188600
109 + 188491 = 188600
127 + 188473 = 188600
157 + 188443 = 188600
163 + 188437 = 188600
193 + 188407 = 188600

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 188,600 and was likely granted around 1875.

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