Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679990, here are decompositions:

17 + 8679973 = 8679990
19 + 8679971 = 8679990
37 + 8679953 = 8679990
47 + 8679943 = 8679990
103 + 8679887 = 8679990
107 + 8679883 = 8679990
149 + 8679841 = 8679990
199 + 8679791 = 8679990

Showing the first eight; more decompositions exist.
