Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140020, here are decompositions:

11 + 140009 = 140020
29 + 139991 = 140020
53 + 139967 = 140020
113 + 139907 = 140020
137 + 139883 = 140020
149 + 139871 = 140020
233 + 139787 = 140020
281 + 139739 = 140020

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 140,020 and was likely granted around 1872.

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