Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616784, here are decompositions:

3 + 8616781 = 8616784
23 + 8616761 = 8616784
131 + 8616653 = 8616784
251 + 8616533 = 8616784
257 + 8616527 = 8616784
353 + 8616431 = 8616784
431 + 8616353 = 8616784
461 + 8616323 = 8616784

Showing the first eight; more decompositions exist.
