Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602166, here are decompositions:

3 + 31602163 = 31602166
23 + 31602143 = 31602166
149 + 31602017 = 31602166
179 + 31601987 = 31602166
269 + 31601897 = 31602166
293 + 31601873 = 31602166
317 + 31601849 = 31602166
347 + 31601819 = 31602166

Showing the first eight; more decompositions exist.
