Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606664, here are decompositions:

7 + 8606657 = 8606664
43 + 8606621 = 8606664
61 + 8606603 = 8606664
107 + 8606557 = 8606664
127 + 8606537 = 8606664
137 + 8606527 = 8606664
163 + 8606501 = 8606664
173 + 8606491 = 8606664

Showing the first eight; more decompositions exist.
