Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679680, here are decompositions:

3 + 8679677 = 8679680
73 + 8679607 = 8679680
151 + 8679529 = 8679680
181 + 8679499 = 8679680
223 + 8679457 = 8679680
283 + 8679397 = 8679680
307 + 8679373 = 8679680
409 + 8679271 = 8679680

Showing the first eight; more decompositions exist.
