Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660664, here are decompositions:

7 + 8660657 = 8660664
11 + 8660653 = 8660664
41 + 8660623 = 8660664
53 + 8660611 = 8660664
127 + 8660537 = 8660664
137 + 8660527 = 8660664
157 + 8660507 = 8660664
197 + 8660467 = 8660664

Showing the first eight; more decompositions exist.
