Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602016, here are decompositions:

29 + 31601987 = 31602016
167 + 31601849 = 31602016
179 + 31601837 = 31602016
197 + 31601819 = 31602016
233 + 31601783 = 31602016
293 + 31601723 = 31602016
317 + 31601699 = 31602016
449 + 31601567 = 31602016

Showing the first eight; more decompositions exist.
