Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647568, here are decompositions:

31 + 8647537 = 8647568
37 + 8647531 = 8647568
67 + 8647501 = 8647568
109 + 8647459 = 8647568
151 + 8647417 = 8647568
157 + 8647411 = 8647568
199 + 8647369 = 8647568
337 + 8647231 = 8647568

Showing the first eight; more decompositions exist.
