Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679872, here are decompositions:

31 + 8679841 = 8679872
163 + 8679709 = 8679872
373 + 8679499 = 8679872
499 + 8679373 = 8679872
601 + 8679271 = 8679872
673 + 8679199 = 8679872
1009 + 8678863 = 8679872
1021 + 8678851 = 8679872

Showing the first eight; more decompositions exist.
