Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008690, here are decompositions:

31 + 1008659 = 1008690
73 + 1008617 = 1008690
79 + 1008611 = 1008690
83 + 1008607 = 1008690
101 + 1008589 = 1008690
103 + 1008587 = 1008690
127 + 1008563 = 1008690
149 + 1008541 = 1008690

Showing the first eight; more decompositions exist.
