Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660690, here are decompositions:

7 + 8660683 = 8660690
19 + 8660671 = 8660690
37 + 8660653 = 8660690
67 + 8660623 = 8660690
79 + 8660611 = 8660690
151 + 8660539 = 8660690
163 + 8660527 = 8660690
223 + 8660467 = 8660690

Showing the first eight; more decompositions exist.
