Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502296, here are decompositions:

17 + 31502279 = 31502296
53 + 31502243 = 31502296
83 + 31502213 = 31502296
107 + 31502189 = 31502296
113 + 31502183 = 31502296
149 + 31502147 = 31502296
167 + 31502129 = 31502296
197 + 31502099 = 31502296

Showing the first eight; more decompositions exist.
