Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047858, here are decompositions:

17 + 1047841 = 1047858
37 + 1047821 = 1047858
79 + 1047779 = 1047858
107 + 1047751 = 1047858
137 + 1047721 = 1047858
157 + 1047701 = 1047858
167 + 1047691 = 1047858
191 + 1047667 = 1047858

Showing the first eight; more decompositions exist.
