Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723548, here are decompositions:

17 + 8723531 = 8723548
89 + 8723459 = 8723548
107 + 8723441 = 8723548
149 + 8723399 = 8723548
227 + 8723321 = 8723548
467 + 8723081 = 8723548
557 + 8722991 = 8723548
599 + 8722949 = 8723548

Showing the first eight; more decompositions exist.
