Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538858, here are decompositions:

17 + 538841 = 538858
29 + 538829 = 538858
41 + 538817 = 538858
59 + 538799 = 538858
107 + 538751 = 538858
137 + 538721 = 538858
149 + 538709 = 538858
269 + 538589 = 538858

Showing the first eight; more decompositions exist.
