Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140286, here are decompositions:

5 + 140281 = 140286
17 + 140269 = 140286
23 + 140263 = 140286
37 + 140249 = 140286
59 + 140227 = 140286
79 + 140207 = 140286
89 + 140197 = 140286
109 + 140177 = 140286

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 140,286 and was likely granted around 1872.

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