Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582288, here are decompositions:

47 + 31582241 = 31582288
71 + 31582217 = 31582288
167 + 31582121 = 31582288
191 + 31582097 = 31582288
239 + 31582049 = 31582288
251 + 31582037 = 31582288
509 + 31581779 = 31582288
557 + 31581731 = 31582288

Showing the first eight; more decompositions exist.
