Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136440, here are decompositions:

11 + 136429 = 136440
19 + 136421 = 136440
23 + 136417 = 136440
37 + 136403 = 136440
41 + 136399 = 136440
43 + 136397 = 136440
47 + 136393 = 136440
61 + 136379 = 136440

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 136,440 and was likely granted around 1872.

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