Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008978, here are decompositions:

31 + 1008947 = 1008978
41 + 1008937 = 1008978
67 + 1008911 = 1008978
107 + 1008871 = 1008978
127 + 1008851 = 1008978
149 + 1008829 = 1008978
197 + 1008781 = 1008978
199 + 1008779 = 1008978

Showing the first eight; more decompositions exist.
