Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185008, here are decompositions:

11 + 184997 = 185008
41 + 184967 = 185008
59 + 184949 = 185008
107 + 184901 = 185008
149 + 184859 = 185008
179 + 184829 = 185008
281 + 184727 = 185008
359 + 184649 = 185008

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 185,008 and was likely granted around 1875.

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