Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100866, here are decompositions:

13 + 100853 = 100866
19 + 100847 = 100866
37 + 100829 = 100866
43 + 100823 = 100866
67 + 100799 = 100866
79 + 100787 = 100866
97 + 100769 = 100866
163 + 100703 = 100866

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 100,866 and was likely granted around 1870.

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