Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718944, here are decompositions:

37 + 8718907 = 8718944
67 + 8718877 = 8718944
151 + 8718793 = 8718944
211 + 8718733 = 8718944
271 + 8718673 = 8718944
373 + 8718571 = 8718944
457 + 8718487 = 8718944
601 + 8718343 = 8718944

Showing the first eight; more decompositions exist.
