Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139410, here are decompositions:

13 + 139397 = 139410
17 + 139393 = 139410
23 + 139387 = 139410
41 + 139369 = 139410
43 + 139367 = 139410
67 + 139343 = 139410
71 + 139339 = 139410
97 + 139313 = 139410

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 139,410 and was likely granted around 1872.

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