Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100164, here are decompositions:

11 + 100153 = 100164
13 + 100151 = 100164
61 + 100103 = 100164
107 + 100057 = 100164
173 + 99991 = 100164
193 + 99971 = 100164
241 + 99923 = 100164
257 + 99907 = 100164

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 100,164 and was likely granted around 1870.

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