Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679020, here are decompositions:

73 + 8678947 = 8679020
79 + 8678941 = 8679020
127 + 8678893 = 8679020
157 + 8678863 = 8679020
199 + 8678821 = 8679020
241 + 8678779 = 8679020
271 + 8678749 = 8679020
307 + 8678713 = 8679020

Showing the first eight; more decompositions exist.
