Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649730, here are decompositions:

41 + 8649689 = 8649730
53 + 8649677 = 8649730
59 + 8649671 = 8649730
101 + 8649629 = 8649730
107 + 8649623 = 8649730
149 + 8649581 = 8649730
197 + 8649533 = 8649730
239 + 8649491 = 8649730

Showing the first eight; more decompositions exist.
