Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104864, here are decompositions:

13 + 104851 = 104864
37 + 104827 = 104864
61 + 104803 = 104864
103 + 104761 = 104864
157 + 104707 = 104864
163 + 104701 = 104864
181 + 104683 = 104864
241 + 104623 = 104864

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 104 864 and was likely granted around 1870.

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