Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121250, here are decompositions:

61 + 121189 = 121250
79 + 121171 = 121250
127 + 121123 = 121250
211 + 121039 = 121250
229 + 121021 = 121250
307 + 120943 = 121250
313 + 120937 = 121250
331 + 120919 = 121250

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 121,250 and was likely granted around 1871.

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