Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649924, here are decompositions:

13 + 8649911 = 8649924
37 + 8649887 = 8649924
43 + 8649881 = 8649924
53 + 8649871 = 8649924
67 + 8649857 = 8649924
71 + 8649853 = 8649924
131 + 8649793 = 8649924
163 + 8649761 = 8649924

Showing the first eight; more decompositions exist.
