Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649684, here are decompositions:

7 + 8649677 = 8649684
13 + 8649671 = 8649684
23 + 8649661 = 8649684
47 + 8649637 = 8649684
61 + 8649623 = 8649684
73 + 8649611 = 8649684
103 + 8649581 = 8649684
151 + 8649533 = 8649684

Showing the first eight; more decompositions exist.
