Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679808, here are decompositions:

17 + 8679791 = 8679808
41 + 8679767 = 8679808
131 + 8679677 = 8679808
167 + 8679641 = 8679808
191 + 8679617 = 8679808
227 + 8679581 = 8679808
251 + 8679557 = 8679808
257 + 8679551 = 8679808

Showing the first eight; more decompositions exist.
