Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723944, here are decompositions:

11 + 8723933 = 8723944
23 + 8723921 = 8723944
41 + 8723903 = 8723944
137 + 8723807 = 8723944
461 + 8723483 = 8723944
503 + 8723441 = 8723944
521 + 8723423 = 8723944
557 + 8723387 = 8723944

Showing the first eight; more decompositions exist.
