Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9958, here are decompositions:

17 + 9941 = 9958
29 + 9929 = 9958
71 + 9887 = 9958
101 + 9857 = 9958
107 + 9851 = 9958
167 + 9791 = 9958
191 + 9767 = 9958
239 + 9719 = 9958

Showing the first eight; more decompositions exist.
