Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690000, here are decompositions:

3 + 8689997 = 8690000
13 + 8689987 = 8690000
19 + 8689981 = 8690000
31 + 8689969 = 8690000
43 + 8689957 = 8690000
157 + 8689843 = 8690000
223 + 8689777 = 8690000
271 + 8689729 = 8690000

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 8,690,000 and was likely granted around 2014.

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