Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100066, here are decompositions:

17 + 100049 = 100066
23 + 100043 = 100066
47 + 100019 = 100066
137 + 99929 = 100066
227 + 99839 = 100066
233 + 99833 = 100066
257 + 99809 = 100066
347 + 99719 = 100066

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 100,066 and was likely granted around 1870.

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