Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17958, here are decompositions:

19 + 17939 = 17958
29 + 17929 = 17958
37 + 17921 = 17958
47 + 17911 = 17958
67 + 17891 = 17958
107 + 17851 = 17958
131 + 17827 = 17958
151 + 17807 = 17958

Showing the first eight; more decompositions exist.
