Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966666, here are decompositions:

5 + 966661 = 966666
7 + 966659 = 966666
13 + 966653 = 966666
47 + 966619 = 966666
53 + 966613 = 966666
83 + 966583 = 966666
109 + 966557 = 966666
139 + 966527 = 966666

Showing the first eight; more decompositions exist.
