Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008784, here are decompositions:

3 + 1008781 = 1008784
5 + 1008779 = 1008784
11 + 1008773 = 1008784
41 + 1008743 = 1008784
83 + 1008701 = 1008784
167 + 1008617 = 1008784
173 + 1008611 = 1008784
197 + 1008587 = 1008784

Showing the first eight; more decompositions exist.
