Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649786, here are decompositions:

23 + 8649763 = 8649786
29 + 8649757 = 8649786
83 + 8649703 = 8649786
97 + 8649689 = 8649786
109 + 8649677 = 8649786
149 + 8649637 = 8649786
157 + 8649629 = 8649786
163 + 8649623 = 8649786

Showing the first eight; more decompositions exist.
