Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135230, here are decompositions:

19 + 135211 = 135230
37 + 135193 = 135230
79 + 135151 = 135230
181 + 135049 = 135230
211 + 135019 = 135230
223 + 135007 = 135230
241 + 134989 = 135230
283 + 134947 = 135230

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 135,230 and was likely granted around 1872.

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