Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678724, here are decompositions:

11 + 8678713 = 8678724
17 + 8678707 = 8678724
23 + 8678701 = 8678724
31 + 8678693 = 8678724
53 + 8678671 = 8678724
137 + 8678587 = 8678724
167 + 8678557 = 8678724
251 + 8678473 = 8678724

Showing the first eight; more decompositions exist.
