Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698664, here are decompositions:

31 + 8698633 = 8698664
43 + 8698621 = 8698664
61 + 8698603 = 8698664
67 + 8698597 = 8698664
367 + 8698297 = 8698664
571 + 8698093 = 8698664
691 + 8697973 = 8698664
727 + 8697937 = 8698664

Showing the first eight; more decompositions exist.
