Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104020, here are decompositions:

11 + 104009 = 104020
17 + 104003 = 104020
23 + 103997 = 104020
29 + 103991 = 104020
41 + 103979 = 104020
53 + 103967 = 104020
101 + 103919 = 104020
107 + 103913 = 104020

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 104,020 and was likely granted around 1870.

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