Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679380, here are decompositions:

7 + 8679373 = 8679380
103 + 8679277 = 8679380
109 + 8679271 = 8679380
163 + 8679217 = 8679380
181 + 8679199 = 8679380
271 + 8679109 = 8679380
433 + 8678947 = 8679380
439 + 8678941 = 8679380

Showing the first eight; more decompositions exist.
