Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162988, here are decompositions:

17 + 162971 = 162988
41 + 162947 = 162988
71 + 162917 = 162988
107 + 162881 = 162988
149 + 162839 = 162988
167 + 162821 = 162988
197 + 162791 = 162988
239 + 162749 = 162988

Showing the first eight; more decompositions exist.
