Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602156, here are decompositions:

13 + 31602143 = 31602156
59 + 31602097 = 31602156
107 + 31602049 = 31602156
139 + 31602017 = 31602156
233 + 31601923 = 31602156
283 + 31601873 = 31602156
293 + 31601863 = 31602156
307 + 31601849 = 31602156

Showing the first eight; more decompositions exist.
