Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104840, here are decompositions:

13 + 104827 = 104840
37 + 104803 = 104840
61 + 104779 = 104840
67 + 104773 = 104840
79 + 104761 = 104840
97 + 104743 = 104840
139 + 104701 = 104840
157 + 104683 = 104840

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 104.840 and was likely granted around 1870.

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