Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502232, here are decompositions:

19 + 31502213 = 31502232
43 + 31502189 = 31502232
71 + 31502161 = 31502232
101 + 31502131 = 31502232
103 + 31502129 = 31502232
149 + 31502083 = 31502232
353 + 31501879 = 31502232
383 + 31501849 = 31502232

Showing the first eight; more decompositions exist.
