Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602216, here are decompositions:

43 + 31602173 = 31602216
53 + 31602163 = 31602216
73 + 31602143 = 31602216
137 + 31602079 = 31602216
167 + 31602049 = 31602216
199 + 31602017 = 31602216
229 + 31601987 = 31602216
293 + 31601923 = 31602216

Showing the first eight; more decompositions exist.
