Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679930, here are decompositions:

31 + 8679899 = 8679930
43 + 8679887 = 8679930
47 + 8679883 = 8679930
59 + 8679871 = 8679930
89 + 8679841 = 8679930
139 + 8679791 = 8679930
163 + 8679767 = 8679930
191 + 8679739 = 8679930

Showing the first eight; more decompositions exist.
