Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647980, here are decompositions:

13 + 8647967 = 8647980
17 + 8647963 = 8647980
31 + 8647949 = 8647980
43 + 8647937 = 8647980
53 + 8647927 = 8647980
67 + 8647913 = 8647980
83 + 8647897 = 8647980
101 + 8647879 = 8647980

Showing the first eight; more decompositions exist.
