Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123112, here are decompositions:

29 + 123083 = 123112
53 + 123059 = 123112
149 + 122963 = 123112
173 + 122939 = 123112
191 + 122921 = 123112
251 + 122861 = 123112
263 + 122849 = 123112
293 + 122819 = 123112

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 123,112 and was likely granted around 1871.

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