Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669566, here are decompositions:

23 + 8669543 = 8669566
53 + 8669513 = 8669566
83 + 8669483 = 8669566
89 + 8669477 = 8669566
149 + 8669417 = 8669566
167 + 8669399 = 8669566
173 + 8669393 = 8669566
233 + 8669333 = 8669566

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 8,669,566 and was likely granted around 2014.

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