Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649664, here are decompositions:

3 + 8649661 = 8649664
41 + 8649623 = 8649664
53 + 8649611 = 8649664
83 + 8649581 = 8649664
131 + 8649533 = 8649664
173 + 8649491 = 8649664
197 + 8649467 = 8649664
281 + 8649383 = 8649664

Showing the first eight; more decompositions exist.
