Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649998, here are decompositions:

31 + 8649967 = 8649998
61 + 8649937 = 8649998
127 + 8649871 = 8649998
151 + 8649847 = 8649998
241 + 8649757 = 8649998
277 + 8649721 = 8649998
307 + 8649691 = 8649998
337 + 8649661 = 8649998

Showing the first eight; more decompositions exist.
