Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100836, here are decompositions:

7 + 100829 = 100836
13 + 100823 = 100836
37 + 100799 = 100836
67 + 100769 = 100836
89 + 100747 = 100836
103 + 100733 = 100836
137 + 100699 = 100836
163 + 100673 = 100836

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 100,836 and was likely granted around 1870.

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