Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647590, here are decompositions:

11 + 8647579 = 8647590
23 + 8647567 = 8647590
53 + 8647537 = 8647590
59 + 8647531 = 8647590
79 + 8647511 = 8647590
89 + 8647501 = 8647590
131 + 8647459 = 8647590
173 + 8647417 = 8647590

Showing the first eight; more decompositions exist.
