Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647996, here are decompositions:

3 + 8647993 = 8647996
17 + 8647979 = 8647996
29 + 8647967 = 8647996
47 + 8647949 = 8647996
59 + 8647937 = 8647996
83 + 8647913 = 8647996
107 + 8647889 = 8647996
173 + 8647823 = 8647996

Showing the first eight; more decompositions exist.
