Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008780, here are decompositions:

7 + 1008773 = 1008780
37 + 1008743 = 1008780
61 + 1008719 = 1008780
79 + 1008701 = 1008780
163 + 1008617 = 1008780
167 + 1008613 = 1008780
173 + 1008607 = 1008780
191 + 1008589 = 1008780

Showing the first eight; more decompositions exist.
