Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502196, here are decompositions:

7 + 31502189 = 31502196
13 + 31502183 = 31502196
67 + 31502129 = 31502196
83 + 31502113 = 31502196
97 + 31502099 = 31502196
113 + 31502083 = 31502196
239 + 31501957 = 31502196
283 + 31501913 = 31502196

Showing the first eight; more decompositions exist.
