Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016258, here are decompositions:

31 + 1016227 = 1016258
37 + 1016221 = 1016258
277 + 1015981 = 1016258
367 + 1015891 = 1016258
631 + 1015627 = 1016258
709 + 1015549 = 1016258
751 + 1015507 = 1016258
757 + 1015501 = 1016258

Showing the first eight; more decompositions exist.
