Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123146, here are decompositions:

3 + 123143 = 123146
19 + 123127 = 123146
97 + 123049 = 123146
139 + 123007 = 123146
193 + 122953 = 123146
277 + 122869 = 123146
307 + 122839 = 123146
313 + 122833 = 123146

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 123,146 and was likely granted around 1871.

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