Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140820, here are decompositions:

7 + 140813 = 140820
23 + 140797 = 140820
41 + 140779 = 140820
47 + 140773 = 140820
59 + 140761 = 140820
61 + 140759 = 140820
79 + 140741 = 140820
89 + 140731 = 140820

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 140,820 and was likely granted around 1872.

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