Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649928, here are decompositions:

17 + 8649911 = 8649928
41 + 8649887 = 8649928
47 + 8649881 = 8649928
59 + 8649869 = 8649928
71 + 8649857 = 8649928
137 + 8649791 = 8649928
167 + 8649761 = 8649928
239 + 8649689 = 8649928

Showing the first eight; more decompositions exist.
