Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679218, here are decompositions:

19 + 8679199 = 8679218
109 + 8679109 = 8679218
139 + 8679079 = 8679218
181 + 8679037 = 8679218
271 + 8678947 = 8679218
277 + 8678941 = 8679218
367 + 8678851 = 8679218
397 + 8678821 = 8679218

Showing the first eight; more decompositions exist.
