Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582492, here are decompositions:

3 + 31582489 = 31582492
83 + 31582409 = 31582492
89 + 31582403 = 31582492
173 + 31582319 = 31582492
251 + 31582241 = 31582492
443 + 31582049 = 31582492
449 + 31582043 = 31582492
509 + 31581983 = 31582492

Showing the first eight; more decompositions exist.
