Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678900, here are decompositions:

7 + 8678893 = 8678900
37 + 8678863 = 8678900
67 + 8678833 = 8678900
79 + 8678821 = 8678900
127 + 8678773 = 8678900
151 + 8678749 = 8678900
193 + 8678707 = 8678900
199 + 8678701 = 8678900

Showing the first eight; more decompositions exist.
