Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57958, here are decompositions:

11 + 57947 = 57958
41 + 57917 = 57958
59 + 57899 = 57958
149 + 57809 = 57958
167 + 57791 = 57958
227 + 57731 = 57958
239 + 57719 = 57958
269 + 57689 = 57958

Showing the first eight; more decompositions exist.
