Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008786, here are decompositions:

5 + 1008781 = 1008786
7 + 1008779 = 1008786
13 + 1008773 = 1008786
43 + 1008743 = 1008786
67 + 1008719 = 1008786
127 + 1008659 = 1008786
173 + 1008613 = 1008786
179 + 1008607 = 1008786

Showing the first eight; more decompositions exist.
