Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185600, here are decompositions:

7 + 185593 = 185600
31 + 185569 = 185600
43 + 185557 = 185600
61 + 185539 = 185600
67 + 185533 = 185600
73 + 185527 = 185600
109 + 185491 = 185600
199 + 185401 = 185600

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 185,600 and was likely granted around 1875.

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