Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649906, here are decompositions:

19 + 8649887 = 8649906
37 + 8649869 = 8649906
53 + 8649853 = 8649906
59 + 8649847 = 8649906
103 + 8649803 = 8649906
113 + 8649793 = 8649906
149 + 8649757 = 8649906
229 + 8649677 = 8649906

Showing the first eight; more decompositions exist.
