Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699664, here are decompositions:

5 + 8699659 = 8699664
23 + 8699641 = 8699664
31 + 8699633 = 8699664
53 + 8699611 = 8699664
97 + 8699567 = 8699664
107 + 8699557 = 8699664
131 + 8699533 = 8699664
151 + 8699513 = 8699664

Showing the first eight; more decompositions exist.
