Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723256, here are decompositions:

13 + 8723243 = 8723256
43 + 8723213 = 8723256
53 + 8723203 = 8723256
107 + 8723149 = 8723256
149 + 8723107 = 8723256
167 + 8723089 = 8723256
193 + 8723063 = 8723256
239 + 8723017 = 8723256

Showing the first eight; more decompositions exist.
