Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123250, here are decompositions:

11 + 123239 = 123250
41 + 123209 = 123250
47 + 123203 = 123250
59 + 123191 = 123250
107 + 123143 = 123250
137 + 123113 = 123250
167 + 123083 = 123250
173 + 123077 = 123250

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 123,250 and was likely granted around 1871.

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