Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723436, here are decompositions:

13 + 8723423 = 8723436
17 + 8723419 = 8723436
37 + 8723399 = 8723436
83 + 8723353 = 8723436
89 + 8723347 = 8723436
193 + 8723243 = 8723436
223 + 8723213 = 8723436
233 + 8723203 = 8723436

Showing the first eight; more decompositions exist.
