Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104388, here are decompositions:

5 + 104383 = 104388
7 + 104381 = 104388
19 + 104369 = 104388
41 + 104347 = 104388
61 + 104327 = 104388
79 + 104309 = 104388
101 + 104287 = 104388
107 + 104281 = 104388

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 104 388 and was likely granted around 1870.

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