Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121130, here are decompositions:

7 + 121123 = 121130
67 + 121063 = 121130
109 + 121021 = 121130
193 + 120937 = 121130
211 + 120919 = 121130
223 + 120907 = 121130
241 + 120889 = 121130
283 + 120847 = 121130

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 121,130 and was likely granted around 1871.

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