Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738218, here are decompositions:

17 + 8738201 = 8738218
89 + 8738129 = 8738218
131 + 8738087 = 8738218
239 + 8737979 = 8738218
347 + 8737871 = 8738218
389 + 8737829 = 8738218
509 + 8737709 = 8738218
521 + 8737697 = 8738218

Showing the first eight; more decompositions exist.
