Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723318, here are decompositions:

7 + 8723311 = 8723318
127 + 8723191 = 8723318
181 + 8723137 = 8723318
211 + 8723107 = 8723318
229 + 8723089 = 8723318
271 + 8723047 = 8723318
277 + 8723041 = 8723318
337 + 8722981 = 8723318

Showing the first eight; more decompositions exist.
