Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683840, here are decompositions:

17 + 8683823 = 8683840
47 + 8683793 = 8683840
59 + 8683781 = 8683840
71 + 8683769 = 8683840
83 + 8683757 = 8683840
149 + 8683691 = 8683840
227 + 8683613 = 8683840
233 + 8683607 = 8683840

Showing the first eight; more decompositions exist.
