Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647584, here are decompositions:

5 + 8647579 = 8647584
17 + 8647567 = 8647584
47 + 8647537 = 8647584
53 + 8647531 = 8647584
73 + 8647511 = 8647584
83 + 8647501 = 8647584
137 + 8647447 = 8647584
167 + 8647417 = 8647584

Showing the first eight; more decompositions exist.
