Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649788, here are decompositions:

31 + 8649757 = 8649788
67 + 8649721 = 8649788
97 + 8649691 = 8649788
127 + 8649661 = 8649788
151 + 8649637 = 8649788
271 + 8649517 = 8649788
337 + 8649451 = 8649788
379 + 8649409 = 8649788

Showing the first eight; more decompositions exist.
