Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602320, here are decompositions:

3 + 31602317 = 31602320
103 + 31602217 = 31602320
157 + 31602163 = 31602320
199 + 31602121 = 31602320
223 + 31602097 = 31602320
241 + 31602079 = 31602320
271 + 31602049 = 31602320
397 + 31601923 = 31602320

Showing the first eight; more decompositions exist.
