Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649984, here are decompositions:

11 + 8649973 = 8649984
17 + 8649967 = 8649984
47 + 8649937 = 8649984
73 + 8649911 = 8649984
97 + 8649887 = 8649984
103 + 8649881 = 8649984
113 + 8649871 = 8649984
127 + 8649857 = 8649984

Showing the first eight; more decompositions exist.
