Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679186, here are decompositions:

7 + 8679179 = 8679186
107 + 8679079 = 8679186
127 + 8679059 = 8679186
149 + 8679037 = 8679186
223 + 8678963 = 8679186
239 + 8678947 = 8679186
283 + 8678903 = 8679186
293 + 8678893 = 8679186

Showing the first eight; more decompositions exist.
