Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100864, here are decompositions:

11 + 100853 = 100864
17 + 100847 = 100864
41 + 100823 = 100864
53 + 100811 = 100864
131 + 100733 = 100864
191 + 100673 = 100864
251 + 100613 = 100864
317 + 100547 = 100864

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 100,864 and was likely granted around 1870.

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