Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647926, here are decompositions:

13 + 8647913 = 8647926
29 + 8647897 = 8647926
37 + 8647889 = 8647926
47 + 8647879 = 8647926
103 + 8647823 = 8647926
107 + 8647819 = 8647926
109 + 8647817 = 8647926
167 + 8647759 = 8647926

Showing the first eight; more decompositions exist.
