Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621118, here are decompositions:

17 + 8621101 = 8621118
29 + 8621089 = 8621118
31 + 8621087 = 8621118
41 + 8621077 = 8621118
67 + 8621051 = 8621118
71 + 8621047 = 8621118
101 + 8621017 = 8621118
109 + 8621009 = 8621118

Showing the first eight; more decompositions exist.
