Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159888, here are decompositions:

17 + 159871 = 159888
19 + 159869 = 159888
31 + 159857 = 159888
89 + 159799 = 159888
97 + 159791 = 159888
101 + 159787 = 159888
109 + 159779 = 159888
149 + 159739 = 159888

Showing the first eight; more decompositions exist.
