Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602230, here are decompositions:

3 + 31602227 = 31602230
13 + 31602217 = 31602230
67 + 31602163 = 31602230
109 + 31602121 = 31602230
151 + 31602079 = 31602230
181 + 31602049 = 31602230
307 + 31601923 = 31602230
349 + 31601881 = 31602230

Showing the first eight; more decompositions exist.
