Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723418, here are decompositions:

19 + 8723399 = 8723418
31 + 8723387 = 8723418
59 + 8723359 = 8723418
71 + 8723347 = 8723418
97 + 8723321 = 8723418
101 + 8723317 = 8723418
107 + 8723311 = 8723418
227 + 8723191 = 8723418

Showing the first eight; more decompositions exist.
