Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618118, here are decompositions:

11 + 8618107 = 8618118
29 + 8618089 = 8618118
31 + 8618087 = 8618118
59 + 8618059 = 8618118
71 + 8618047 = 8618118
97 + 8618021 = 8618118
127 + 8617991 = 8618118
191 + 8617927 = 8618118

Showing the first eight; more decompositions exist.
