Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647916, here are decompositions:

3 + 8647913 = 8647916
19 + 8647897 = 8647916
37 + 8647879 = 8647916
97 + 8647819 = 8647916
157 + 8647759 = 8647916
163 + 8647753 = 8647916
337 + 8647579 = 8647916
349 + 8647567 = 8647916

Showing the first eight; more decompositions exist.
