Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649682, here are decompositions:

5 + 8649677 = 8649682
11 + 8649671 = 8649682
53 + 8649629 = 8649682
59 + 8649623 = 8649682
71 + 8649611 = 8649682
101 + 8649581 = 8649682
149 + 8649533 = 8649682
191 + 8649491 = 8649682

Showing the first eight; more decompositions exist.
