Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649792, here are decompositions:

29 + 8649763 = 8649792
31 + 8649761 = 8649792
71 + 8649721 = 8649792
89 + 8649703 = 8649792
101 + 8649691 = 8649792
103 + 8649689 = 8649792
131 + 8649661 = 8649792
163 + 8649629 = 8649792

Showing the first eight; more decompositions exist.
