Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723270, here are decompositions:

67 + 8723203 = 8723270
79 + 8723191 = 8723270
163 + 8723107 = 8723270
181 + 8723089 = 8723270
223 + 8723047 = 8723270
229 + 8723041 = 8723270
271 + 8722999 = 8723270
277 + 8722993 = 8723270

Showing the first eight; more decompositions exist.
