Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647000, here are decompositions:

29 + 8646971 = 8647000
53 + 8646947 = 8647000
71 + 8646929 = 8647000
101 + 8646899 = 8647000
149 + 8646851 = 8647000
179 + 8646821 = 8647000
281 + 8646719 = 8647000
293 + 8646707 = 8647000

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 8,647,000 and was likely granted around 2014.

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