Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502410, here are decompositions:

47 + 31502363 = 31502410
131 + 31502279 = 31502410
167 + 31502243 = 31502410
197 + 31502213 = 31502410
227 + 31502183 = 31502410
263 + 31502147 = 31502410
281 + 31502129 = 31502410
311 + 31502099 = 31502410

Showing the first eight; more decompositions exist.
