Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502324, here are decompositions:

13 + 31502311 = 31502324
37 + 31502287 = 31502324
163 + 31502161 = 31502324
193 + 31502131 = 31502324
211 + 31502113 = 31502324
241 + 31502083 = 31502324
367 + 31501957 = 31502324
463 + 31501861 = 31502324

Showing the first eight; more decompositions exist.
