Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678770, here are decompositions:

11 + 8678759 = 8678770
17 + 8678753 = 8678770
29 + 8678741 = 8678770
71 + 8678699 = 8678770
101 + 8678669 = 8678770
131 + 8678639 = 8678770
167 + 8678603 = 8678770
251 + 8678519 = 8678770

Showing the first eight; more decompositions exist.
