Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678828, here are decompositions:

7 + 8678821 = 8678828
79 + 8678749 = 8678828
127 + 8678701 = 8678828
157 + 8678671 = 8678828
229 + 8678599 = 8678828
241 + 8678587 = 8678828
271 + 8678557 = 8678828
877 + 8677951 = 8678828

Showing the first eight; more decompositions exist.
