Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104080, here are decompositions:

47 + 104033 = 104080
59 + 104021 = 104080
71 + 104009 = 104080
83 + 103997 = 104080
89 + 103991 = 104080
101 + 103979 = 104080
113 + 103967 = 104080
167 + 103913 = 104080

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 104,080 and was likely granted around 1870.

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