Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185106, here are decompositions:

7 + 185099 = 185106
17 + 185089 = 185106
29 + 185077 = 185106
37 + 185069 = 185106
43 + 185063 = 185106
79 + 185027 = 185106
107 + 184999 = 185106
109 + 184997 = 185106

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 185,106 and was likely granted around 1875.

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