Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649648, here are decompositions:

11 + 8649637 = 8649648
19 + 8649629 = 8649648
37 + 8649611 = 8649648
67 + 8649581 = 8649648
127 + 8649521 = 8649648
131 + 8649517 = 8649648
157 + 8649491 = 8649648
179 + 8649469 = 8649648

Showing the first eight; more decompositions exist.
