Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723130, here are decompositions:

7 + 8723123 = 8723130
23 + 8723107 = 8723130
41 + 8723089 = 8723130
67 + 8723063 = 8723130
83 + 8723047 = 8723130
89 + 8723041 = 8723130
113 + 8723017 = 8723130
131 + 8722999 = 8723130

Showing the first eight; more decompositions exist.
