Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502202, here are decompositions:

13 + 31502189 = 31502202
19 + 31502183 = 31502202
41 + 31502161 = 31502202
71 + 31502131 = 31502202
73 + 31502129 = 31502202
89 + 31502113 = 31502202
103 + 31502099 = 31502202
223 + 31501979 = 31502202

Showing the first eight; more decompositions exist.
