Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522858, here are decompositions:

5 + 522853 = 522858
19 + 522839 = 522858
29 + 522829 = 522858
31 + 522827 = 522858
47 + 522811 = 522858
71 + 522787 = 522858
97 + 522761 = 522858
101 + 522757 = 522858

Showing the first eight; more decompositions exist.
