Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679988, here are decompositions:

17 + 8679971 = 8679988
89 + 8679899 = 8679988
101 + 8679887 = 8679988
197 + 8679791 = 8679988
311 + 8679677 = 8679988
347 + 8679641 = 8679988
431 + 8679557 = 8679988
461 + 8679527 = 8679988

Showing the first eight; more decompositions exist.
