Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520482, here are decompositions:

3 + 31520479 = 31520482
29 + 31520453 = 31520482
83 + 31520399 = 31520482
89 + 31520393 = 31520482
173 + 31520309 = 31520482
239 + 31520243 = 31520482
281 + 31520201 = 31520482
311 + 31520171 = 31520482

Showing the first eight; more decompositions exist.
