Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679870, here are decompositions:

29 + 8679841 = 8679870
79 + 8679791 = 8679870
103 + 8679767 = 8679870
127 + 8679743 = 8679870
131 + 8679739 = 8679870
193 + 8679677 = 8679870
229 + 8679641 = 8679870
263 + 8679607 = 8679870

Showing the first eight; more decompositions exist.
