Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188040, here are decompositions:

11 + 188029 = 188040
19 + 188021 = 188040
23 + 188017 = 188040
29 + 188011 = 188040
53 + 187987 = 188040
67 + 187973 = 188040
89 + 187951 = 188040
109 + 187931 = 188040

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 188,040 and was likely granted around 1875.

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