Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008816, here are decompositions:

7 + 1008809 = 1008816
23 + 1008793 = 1008816
37 + 1008779 = 1008816
43 + 1008773 = 1008816
73 + 1008743 = 1008816
97 + 1008719 = 1008816
157 + 1008659 = 1008816
199 + 1008617 = 1008816

Showing the first eight; more decompositions exist.
