Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678984, here are decompositions:

37 + 8678947 = 8678984
43 + 8678941 = 8678984
151 + 8678833 = 8678984
163 + 8678821 = 8678984
211 + 8678773 = 8678984
271 + 8678713 = 8678984
277 + 8678707 = 8678984
283 + 8678701 = 8678984

Showing the first eight; more decompositions exist.
