Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656470, here are decompositions:

7 + 8656463 = 8656470
37 + 8656433 = 8656470
47 + 8656423 = 8656470
59 + 8656411 = 8656470
71 + 8656399 = 8656470
101 + 8656369 = 8656470
103 + 8656367 = 8656470
107 + 8656363 = 8656470

Showing the first eight; more decompositions exist.
