Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679942, here are decompositions:

43 + 8679899 = 8679942
59 + 8679883 = 8679942
71 + 8679871 = 8679942
101 + 8679841 = 8679942
151 + 8679791 = 8679942
199 + 8679743 = 8679942
233 + 8679709 = 8679942
443 + 8679499 = 8679942

Showing the first eight; more decompositions exist.
