Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646906, here are decompositions:

7 + 8646899 = 8646906
17 + 8646889 = 8646906
53 + 8646853 = 8646906
83 + 8646823 = 8646906
89 + 8646817 = 8646906
113 + 8646793 = 8646906
127 + 8646779 = 8646906
197 + 8646709 = 8646906

Showing the first eight; more decompositions exist.
