Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723148, here are decompositions:

11 + 8723137 = 8723148
41 + 8723107 = 8723148
59 + 8723089 = 8723148
67 + 8723081 = 8723148
101 + 8723047 = 8723148
107 + 8723041 = 8723148
131 + 8723017 = 8723148
149 + 8722999 = 8723148

Showing the first eight; more decompositions exist.
