Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502416, here are decompositions:

53 + 31502363 = 31502416
83 + 31502333 = 31502416
137 + 31502279 = 31502416
173 + 31502243 = 31502416
227 + 31502189 = 31502416
233 + 31502183 = 31502416
269 + 31502147 = 31502416
317 + 31502099 = 31502416

Showing the first eight; more decompositions exist.
