Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723226, here are decompositions:

13 + 8723213 = 8723226
23 + 8723203 = 8723226
89 + 8723137 = 8723226
103 + 8723123 = 8723226
137 + 8723089 = 8723226
163 + 8723063 = 8723226
173 + 8723053 = 8723226
179 + 8723047 = 8723226

Showing the first eight; more decompositions exist.
