Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679216, here are decompositions:

17 + 8679199 = 8679216
23 + 8679193 = 8679216
37 + 8679179 = 8679216
79 + 8679137 = 8679216
107 + 8679109 = 8679216
137 + 8679079 = 8679216
157 + 8679059 = 8679216
179 + 8679037 = 8679216

Showing the first eight; more decompositions exist.
