Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655808, here are decompositions:

47 + 8655761 = 8655808
59 + 8655749 = 8655808
89 + 8655719 = 8655808
101 + 8655707 = 8655808
107 + 8655701 = 8655808
131 + 8655677 = 8655808
137 + 8655671 = 8655808
167 + 8655641 = 8655808

Showing the first eight; more decompositions exist.
