Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679140, here are decompositions:

3 + 8679137 = 8679140
31 + 8679109 = 8679140
61 + 8679079 = 8679140
103 + 8679037 = 8679140
193 + 8678947 = 8679140
199 + 8678941 = 8679140
241 + 8678899 = 8679140
277 + 8678863 = 8679140

Showing the first eight; more decompositions exist.
