Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123164, here are decompositions:

37 + 123127 = 123164
43 + 123121 = 123164
73 + 123091 = 123164
157 + 123007 = 123164
163 + 123001 = 123164
193 + 122971 = 123164
211 + 122953 = 123164
277 + 122887 = 123164

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 123,164 and was likely granted around 1871.

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