Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679978, here are decompositions:

5 + 8679973 = 8679978
7 + 8679971 = 8679978
79 + 8679899 = 8679978
107 + 8679871 = 8679978
137 + 8679841 = 8679978
211 + 8679767 = 8679978
239 + 8679739 = 8679978
269 + 8679709 = 8679978

Showing the first eight; more decompositions exist.
