Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679970, here are decompositions:

17 + 8679953 = 8679970
71 + 8679899 = 8679970
83 + 8679887 = 8679970
179 + 8679791 = 8679970
227 + 8679743 = 8679970
293 + 8679677 = 8679970
353 + 8679617 = 8679970
389 + 8679581 = 8679970

Showing the first eight; more decompositions exist.
