Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723168, here are decompositions:

19 + 8723149 = 8723168
31 + 8723137 = 8723168
61 + 8723107 = 8723168
79 + 8723089 = 8723168
127 + 8723041 = 8723168
151 + 8723017 = 8723168
199 + 8722969 = 8723168
277 + 8722891 = 8723168

Showing the first eight; more decompositions exist.
