Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582066, here are decompositions:

17 + 31582049 = 31582066
23 + 31582043 = 31582066
29 + 31582037 = 31582066
83 + 31581983 = 31582066
359 + 31581707 = 31582066
389 + 31581677 = 31582066
443 + 31581623 = 31582066
449 + 31581617 = 31582066

Showing the first eight; more decompositions exist.
