Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602240, here are decompositions:

13 + 31602227 = 31602240
23 + 31602217 = 31602240
67 + 31602173 = 31602240
97 + 31602143 = 31602240
191 + 31602049 = 31602240
199 + 31602041 = 31602240
223 + 31602017 = 31602240
317 + 31601923 = 31602240

Showing the first eight; more decompositions exist.
