Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162858, here are decompositions:

5 + 162853 = 162858
11 + 162847 = 162858
19 + 162839 = 162858
29 + 162829 = 162858
37 + 162821 = 162858
67 + 162791 = 162858
71 + 162787 = 162858
79 + 162779 = 162858

Showing the first eight; more decompositions exist.
