Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738728, here are decompositions:

17 + 8738711 = 8738728
137 + 8738591 = 8738728
149 + 8738579 = 8738728
281 + 8738447 = 8738728
389 + 8738339 = 8738728
599 + 8738129 = 8738728
641 + 8738087 = 8738728
857 + 8737871 = 8738728

Showing the first eight; more decompositions exist.
