Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679220, here are decompositions:

3 + 8679217 = 8679220
41 + 8679179 = 8679220
83 + 8679137 = 8679220
149 + 8679071 = 8679220
257 + 8678963 = 8679220
269 + 8678951 = 8679220
281 + 8678939 = 8679220
293 + 8678927 = 8679220

Showing the first eight; more decompositions exist.
