Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008858, here are decompositions:

5 + 1008853 = 1008858
7 + 1008851 = 1008858
29 + 1008829 = 1008858
41 + 1008817 = 1008858
79 + 1008779 = 1008858
139 + 1008719 = 1008858
157 + 1008701 = 1008858
199 + 1008659 = 1008858

Showing the first eight; more decompositions exist.
