Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679440, here are decompositions:

13 + 8679427 = 8679440
43 + 8679397 = 8679440
61 + 8679379 = 8679440
67 + 8679373 = 8679440
151 + 8679289 = 8679440
163 + 8679277 = 8679440
223 + 8679217 = 8679440
241 + 8679199 = 8679440

Showing the first eight; more decompositions exist.
