Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140454, here are decompositions:

5 + 140449 = 140454
11 + 140443 = 140454
31 + 140423 = 140454
37 + 140417 = 140454
43 + 140411 = 140454
47 + 140407 = 140454
53 + 140401 = 140454
73 + 140381 = 140454

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 140,454 and was likely granted around 1872.

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