Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723968, here are decompositions:

17 + 8723951 = 8723968
47 + 8723921 = 8723968
59 + 8723909 = 8723968
89 + 8723879 = 8723968
179 + 8723789 = 8723968
359 + 8723609 = 8723968
509 + 8723459 = 8723968
569 + 8723399 = 8723968

Showing the first eight; more decompositions exist.
