Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130122, here are decompositions:

23 + 130099 = 130122
43 + 130079 = 130122
53 + 130069 = 130122
71 + 130051 = 130122
79 + 130043 = 130122
101 + 130021 = 130122
151 + 129971 = 130122
163 + 129959 = 130122

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 130,122 and was likely granted around 1872.

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