Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104180, here are decompositions:

7 + 104173 = 104180
19 + 104161 = 104180
31 + 104149 = 104180
61 + 104119 = 104180
67 + 104113 = 104180
73 + 104107 = 104180
127 + 104053 = 104180
199 + 103981 = 104180

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 104,180 and was likely granted around 1870.

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