Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647506, here are decompositions:

5 + 8647501 = 8647506
37 + 8647469 = 8647506
47 + 8647459 = 8647506
59 + 8647447 = 8647506
89 + 8647417 = 8647506
97 + 8647409 = 8647506
113 + 8647393 = 8647506
137 + 8647369 = 8647506

Showing the first eight; more decompositions exist.
