Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649774, here are decompositions:

11 + 8649763 = 8649774
13 + 8649761 = 8649774
17 + 8649757 = 8649774
53 + 8649721 = 8649774
71 + 8649703 = 8649774
83 + 8649691 = 8649774
97 + 8649677 = 8649774
103 + 8649671 = 8649774

Showing the first eight; more decompositions exist.
