Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616840, here are decompositions:

7 + 8616833 = 8616840
13 + 8616827 = 8616840
19 + 8616821 = 8616840
31 + 8616809 = 8616840
59 + 8616781 = 8616840
79 + 8616761 = 8616840
83 + 8616757 = 8616840
107 + 8616733 = 8616840

Showing the first eight; more decompositions exist.
