Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723574, here are decompositions:

5 + 8723569 = 8723574
23 + 8723551 = 8723574
43 + 8723531 = 8723574
53 + 8723521 = 8723574
137 + 8723437 = 8723574
151 + 8723423 = 8723574
227 + 8723347 = 8723574
257 + 8723317 = 8723574

Showing the first eight; more decompositions exist.
