Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185550, here are decompositions:

7 + 185543 = 185550
11 + 185539 = 185550
17 + 185533 = 185550
19 + 185531 = 185550
23 + 185527 = 185550
31 + 185519 = 185550
59 + 185491 = 185550
67 + 185483 = 185550

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 185,550 and was likely granted around 1875.

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