Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185004, here are decompositions:

5 + 184999 = 185004
7 + 184997 = 185004
11 + 184993 = 185004
37 + 184967 = 185004
47 + 184957 = 185004
101 + 184903 = 185004
103 + 184901 = 185004
167 + 184837 = 185004

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 185,004 and was likely granted around 1875.

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