Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679212, here are decompositions:

13 + 8679199 = 8679212
19 + 8679193 = 8679212
103 + 8679109 = 8679212
271 + 8678941 = 8679212
313 + 8678899 = 8679212
349 + 8678863 = 8679212
379 + 8678833 = 8679212
433 + 8678779 = 8679212

Showing the first eight; more decompositions exist.
