Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612784, here are decompositions:

7 + 8612777 = 8612784
17 + 8612767 = 8612784
31 + 8612753 = 8612784
41 + 8612743 = 8612784
53 + 8612731 = 8612784
71 + 8612713 = 8612784
73 + 8612711 = 8612784
83 + 8612701 = 8612784

Showing the first eight; more decompositions exist.
