Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15958, here are decompositions:

71 + 15887 = 15958
149 + 15809 = 15958
167 + 15791 = 15958
191 + 15767 = 15958
197 + 15761 = 15958
227 + 15731 = 15958
311 + 15647 = 15958
317 + 15641 = 15958

Showing the first eight; more decompositions exist.
