Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649708, here are decompositions:

5 + 8649703 = 8649708
17 + 8649691 = 8649708
19 + 8649689 = 8649708
31 + 8649677 = 8649708
37 + 8649671 = 8649708
47 + 8649661 = 8649708
71 + 8649637 = 8649708
79 + 8649629 = 8649708

Showing the first eight; more decompositions exist.
