Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655688, here are decompositions:

11 + 8655677 = 8655688
17 + 8655671 = 8655688
47 + 8655641 = 8655688
59 + 8655629 = 8655688
191 + 8655497 = 8655688
317 + 8655371 = 8655688
401 + 8655287 = 8655688
491 + 8655197 = 8655688

Showing the first eight; more decompositions exist.
