Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140450, here are decompositions:

7 + 140443 = 140450
31 + 140419 = 140450
43 + 140407 = 140450
181 + 140269 = 140450
223 + 140227 = 140450
229 + 140221 = 140450
283 + 140167 = 140450
307 + 140143 = 140450

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 140,450 and was likely granted around 1872.

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