Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013218, here are decompositions:

251 + 1012967 = 1013218
389 + 1012829 = 1013218
449 + 1012769 = 1013218
467 + 1012751 = 1013218
587 + 1012631 = 1013218
599 + 1012619 = 1013218
617 + 1012601 = 1013218
659 + 1012559 = 1013218

Showing the first eight; more decompositions exist.
