Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140408, here are decompositions:

7 + 140401 = 140408
127 + 140281 = 140408
139 + 140269 = 140408
181 + 140227 = 140408
211 + 140197 = 140408
241 + 140167 = 140408
337 + 140071 = 140408
409 + 139999 = 140408

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 140,408 and was likely granted around 1872.

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