Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121050, here are decompositions:

11 + 121039 = 121050
29 + 121021 = 121050
31 + 121019 = 121050
37 + 121013 = 121050
43 + 121007 = 121050
53 + 120997 = 121050
73 + 120977 = 121050
103 + 120947 = 121050

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 121,050 and was likely granted around 1871.

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