Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140040, here are decompositions:

31 + 140009 = 140040
41 + 139999 = 140040
53 + 139987 = 140040
59 + 139981 = 140040
71 + 139969 = 140040
73 + 139967 = 140040
97 + 139943 = 140040
101 + 139939 = 140040

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 140,040 and was likely granted around 1872.

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