Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104812, here are decompositions:

11 + 104801 = 104812
23 + 104789 = 104812
53 + 104759 = 104812
83 + 104729 = 104812
89 + 104723 = 104812
101 + 104711 = 104812
131 + 104681 = 104812
173 + 104639 = 104812

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 104,812 and was likely granted around 1870.

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