Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502214, here are decompositions:

31 + 31502183 = 31502214
53 + 31502161 = 31502214
67 + 31502147 = 31502214
83 + 31502131 = 31502214
101 + 31502113 = 31502214
131 + 31502083 = 31502214
257 + 31501957 = 31502214
277 + 31501937 = 31502214

Showing the first eight; more decompositions exist.
