Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679128, here are decompositions:

19 + 8679109 = 8679128
181 + 8678947 = 8679128
229 + 8678899 = 8679128
277 + 8678851 = 8679128
307 + 8678821 = 8679128
349 + 8678779 = 8679128
379 + 8678749 = 8679128
421 + 8678707 = 8679128

Showing the first eight; more decompositions exist.
