Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656464, here are decompositions:

31 + 8656433 = 8656464
41 + 8656423 = 8656464
53 + 8656411 = 8656464
71 + 8656393 = 8656464
97 + 8656367 = 8656464
101 + 8656363 = 8656464
107 + 8656357 = 8656464
151 + 8656313 = 8656464

Showing the first eight; more decompositions exist.
