Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649970, here are decompositions:

3 + 8649967 = 8649970
41 + 8649929 = 8649970
59 + 8649911 = 8649970
83 + 8649887 = 8649970
89 + 8649881 = 8649970
101 + 8649869 = 8649970
113 + 8649857 = 8649970
167 + 8649803 = 8649970

Showing the first eight; more decompositions exist.
