Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158958, here are decompositions:

17 + 158941 = 158958
31 + 158927 = 158958
109 + 158849 = 158958
167 + 158791 = 158958
181 + 158777 = 158958
197 + 158761 = 158958
199 + 158759 = 158958
211 + 158747 = 158958

Showing the first eight; more decompositions exist.
