Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722944, here are decompositions:

31 + 8722913 = 8722944
53 + 8722891 = 8722944
67 + 8722877 = 8722944
103 + 8722841 = 8722944
233 + 8722711 = 8722944
271 + 8722673 = 8722944
283 + 8722661 = 8722944
313 + 8722631 = 8722944

Showing the first eight; more decompositions exist.
