Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669906, here are decompositions:

13 + 8669893 = 8669906
139 + 8669767 = 8669906
277 + 8669629 = 8669906
283 + 8669623 = 8669906
313 + 8669593 = 8669906
379 + 8669527 = 8669906
463 + 8669443 = 8669906
577 + 8669329 = 8669906

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 8,669,906 and was likely granted around 2014.

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