Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657664, here are decompositions:

13 + 8657651 = 8657664
31 + 8657633 = 8657664
53 + 8657611 = 8657664
97 + 8657567 = 8657664
101 + 8657563 = 8657664
107 + 8657557 = 8657664
131 + 8657533 = 8657664
151 + 8657513 = 8657664

Showing the first eight; more decompositions exist.
