Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140540, here are decompositions:

7 + 140533 = 140540
13 + 140527 = 140540
19 + 140521 = 140540
67 + 140473 = 140540
97 + 140443 = 140540
139 + 140401 = 140540
223 + 140317 = 140540
271 + 140269 = 140540

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 140,540 and was likely granted around 1872.

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