Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679138, here are decompositions:

29 + 8679109 = 8679138
59 + 8679079 = 8679138
67 + 8679071 = 8679138
79 + 8679059 = 8679138
101 + 8679037 = 8679138
191 + 8678947 = 8679138
197 + 8678941 = 8679138
199 + 8678939 = 8679138

Showing the first eight; more decompositions exist.
