Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502312, here are decompositions:

43 + 31502269 = 31502312
151 + 31502161 = 31502312
181 + 31502131 = 31502312
199 + 31502113 = 31502312
229 + 31502083 = 31502312
433 + 31501879 = 31502312
463 + 31501849 = 31502312
571 + 31501741 = 31502312

Showing the first eight; more decompositions exist.
