Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723214, here are decompositions:

11 + 8723203 = 8723214
23 + 8723191 = 8723214
107 + 8723107 = 8723214
151 + 8723063 = 8723214
167 + 8723047 = 8723214
173 + 8723041 = 8723214
197 + 8723017 = 8723214
223 + 8722991 = 8723214

Showing the first eight; more decompositions exist.
