Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185016, here are decompositions:

17 + 184999 = 185016
19 + 184997 = 185016
23 + 184993 = 185016
47 + 184969 = 185016
59 + 184957 = 185016
67 + 184949 = 185016
103 + 184913 = 185016
113 + 184903 = 185016

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 185,016 and was likely granted around 1875.

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