Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679328, here are decompositions:

17 + 8679311 = 8679328
107 + 8679221 = 8679328
149 + 8679179 = 8679328
191 + 8679137 = 8679328
257 + 8679071 = 8679328
269 + 8679059 = 8679328
389 + 8678939 = 8679328
401 + 8678927 = 8679328

Showing the first eight; more decompositions exist.
