Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66958, here are decompositions:

11 + 66947 = 66958
107 + 66851 = 66958
137 + 66821 = 66958
149 + 66809 = 66958
167 + 66791 = 66958
257 + 66701 = 66958
389 + 66569 = 66958
449 + 66509 = 66958

Showing the first eight; more decompositions exist.
