Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018526, here are decompositions:

13 + 1018513 = 1018526
37 + 1018489 = 1018526
79 + 1018447 = 1018526
97 + 1018429 = 1018526
349 + 1018177 = 1018526
709 + 1017817 = 1018526
727 + 1017799 = 1018526
739 + 1017787 = 1018526

Showing the first eight; more decompositions exist.
