Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140430, here are decompositions:

7 + 140423 = 140430
11 + 140419 = 140430
13 + 140417 = 140430
19 + 140411 = 140430
23 + 140407 = 140430
29 + 140401 = 140430
67 + 140363 = 140430
79 + 140351 = 140430

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 140,430 and was likely granted around 1872.

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