Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679998, here are decompositions:

7 + 8679991 = 8679998
127 + 8679871 = 8679998
157 + 8679841 = 8679998
499 + 8679499 = 8679998
541 + 8679457 = 8679998
571 + 8679427 = 8679998
601 + 8679397 = 8679998
619 + 8679379 = 8679998

Showing the first eight; more decompositions exist.
