Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679156, here are decompositions:

19 + 8679137 = 8679156
47 + 8679109 = 8679156
97 + 8679059 = 8679156
193 + 8678963 = 8679156
223 + 8678933 = 8679156
229 + 8678927 = 8679156
257 + 8678899 = 8679156
263 + 8678893 = 8679156

Showing the first eight; more decompositions exist.
