Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185040, here are decompositions:

13 + 185027 = 185040
19 + 185021 = 185040
41 + 184999 = 185040
43 + 184997 = 185040
47 + 184993 = 185040
71 + 184969 = 185040
73 + 184967 = 185040
83 + 184957 = 185040

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 185,040 and was likely granted around 1875.

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