Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123230, here are decompositions:

13 + 123217 = 123230
61 + 123169 = 123230
103 + 123127 = 123230
109 + 123121 = 123230
139 + 123091 = 123230
181 + 123049 = 123230
199 + 123031 = 123230
223 + 123007 = 123230

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 123,230 and was likely granted around 1871.

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