Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679428, here are decompositions:

31 + 8679397 = 8679428
139 + 8679289 = 8679428
151 + 8679277 = 8679428
157 + 8679271 = 8679428
211 + 8679217 = 8679428
229 + 8679199 = 8679428
349 + 8679079 = 8679428
487 + 8678941 = 8679428

Showing the first eight; more decompositions exist.
