Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649988, here are decompositions:

59 + 8649929 = 8649988
101 + 8649887 = 8649988
107 + 8649881 = 8649988
131 + 8649857 = 8649988
197 + 8649791 = 8649988
227 + 8649761 = 8649988
311 + 8649677 = 8649988
317 + 8649671 = 8649988

Showing the first eight; more decompositions exist.
