Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723160, here are decompositions:

11 + 8723149 = 8723160
23 + 8723137 = 8723160
37 + 8723123 = 8723160
53 + 8723107 = 8723160
71 + 8723089 = 8723160
79 + 8723081 = 8723160
97 + 8723063 = 8723160
107 + 8723053 = 8723160

Showing the first eight; more decompositions exist.
