Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017858, here are decompositions:

7 + 1017851 = 1017858
11 + 1017847 = 1017858
31 + 1017827 = 1017858
41 + 1017817 = 1017858
59 + 1017799 = 1017858
71 + 1017787 = 1017858
109 + 1017749 = 1017858
137 + 1017721 = 1017858

Showing the first eight; more decompositions exist.
