Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602256, here are decompositions:

5 + 31602251 = 31602256
17 + 31602239 = 31602256
29 + 31602227 = 31602256
83 + 31602173 = 31602256
113 + 31602143 = 31602256
239 + 31602017 = 31602256
269 + 31601987 = 31602256
359 + 31601897 = 31602256

Showing the first eight; more decompositions exist.
