Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678870, here are decompositions:

7 + 8678863 = 8678870
19 + 8678851 = 8678870
37 + 8678833 = 8678870
97 + 8678773 = 8678870
157 + 8678713 = 8678870
163 + 8678707 = 8678870
199 + 8678671 = 8678870
271 + 8678599 = 8678870

Showing the first eight; more decompositions exist.
