Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649948, here are decompositions:

11 + 8649937 = 8649948
19 + 8649929 = 8649948
37 + 8649911 = 8649948
61 + 8649887 = 8649948
67 + 8649881 = 8649948
79 + 8649869 = 8649948
101 + 8649847 = 8649948
157 + 8649791 = 8649948

Showing the first eight; more decompositions exist.
