Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104140, here are decompositions:

17 + 104123 = 104140
53 + 104087 = 104140
107 + 104033 = 104140
131 + 104009 = 104140
137 + 104003 = 104140
149 + 103991 = 104140
173 + 103967 = 104140
227 + 103913 = 104140

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 104,140 and was likely granted around 1870.

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