Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723118, here are decompositions:

11 + 8723107 = 8723118
29 + 8723089 = 8723118
37 + 8723081 = 8723118
71 + 8723047 = 8723118
101 + 8723017 = 8723118
127 + 8722991 = 8723118
137 + 8722981 = 8723118
149 + 8722969 = 8723118

Showing the first eight; more decompositions exist.
