Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723470, here are decompositions:

11 + 8723459 = 8723470
29 + 8723441 = 8723470
47 + 8723423 = 8723470
71 + 8723399 = 8723470
83 + 8723387 = 8723470
149 + 8723321 = 8723470
167 + 8723303 = 8723470
227 + 8723243 = 8723470

Showing the first eight; more decompositions exist.
