Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582882, here are decompositions:

59 + 31582823 = 31582882
101 + 31582781 = 31582882
251 + 31582631 = 31582882
269 + 31582613 = 31582882
281 + 31582601 = 31582882
293 + 31582589 = 31582882
479 + 31582403 = 31582882
563 + 31582319 = 31582882

Showing the first eight; more decompositions exist.
