Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008868, here are decompositions:

5 + 1008863 = 1008868
11 + 1008857 = 1008868
17 + 1008851 = 1008868
59 + 1008809 = 1008868
89 + 1008779 = 1008868
149 + 1008719 = 1008868
167 + 1008701 = 1008868
251 + 1008617 = 1008868

Showing the first eight; more decompositions exist.
