Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140436, here are decompositions:

13 + 140423 = 140436
17 + 140419 = 140436
19 + 140417 = 140436
29 + 140407 = 140436
73 + 140363 = 140436
97 + 140339 = 140436
103 + 140333 = 140436
139 + 140297 = 140436

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 140,436 and was likely granted around 1872.

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