Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669664, here are decompositions:

7 + 8669657 = 8669664
13 + 8669651 = 8669664
37 + 8669627 = 8669664
41 + 8669623 = 8669664
43 + 8669621 = 8669664
53 + 8669611 = 8669664
71 + 8669593 = 8669664
137 + 8669527 = 8669664

Showing the first eight; more decompositions exist.
