Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723472, here are decompositions:

13 + 8723459 = 8723472
31 + 8723441 = 8723472
53 + 8723419 = 8723472
73 + 8723399 = 8723472
113 + 8723359 = 8723472
151 + 8723321 = 8723472
229 + 8723243 = 8723472
269 + 8723203 = 8723472

Showing the first eight; more decompositions exist.
