Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647524, here are decompositions:

13 + 8647511 = 8647524
23 + 8647501 = 8647524
107 + 8647417 = 8647524
113 + 8647411 = 8647524
131 + 8647393 = 8647524
157 + 8647367 = 8647524
251 + 8647273 = 8647524
271 + 8647253 = 8647524

Showing the first eight; more decompositions exist.
