Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669980, here are decompositions:

17 + 8669963 = 8669980
41 + 8669939 = 8669980
83 + 8669897 = 8669980
101 + 8669879 = 8669980
149 + 8669831 = 8669980
311 + 8669669 = 8669980
353 + 8669627 = 8669980
359 + 8669621 = 8669980

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 8.669.980 and was likely granted around 2014.

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