Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140768, here are decompositions:

7 + 140761 = 140768
37 + 140731 = 140768
79 + 140689 = 140768
109 + 140659 = 140768
139 + 140629 = 140768
151 + 140617 = 140768
157 + 140611 = 140768
181 + 140587 = 140768

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 140,768 and was likely granted around 1872.

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