Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590556, here are decompositions:

5 + 31590551 = 31590556
89 + 31590467 = 31590556
113 + 31590443 = 31590556
293 + 31590263 = 31590556
419 + 31590137 = 31590556
467 + 31590089 = 31590556
797 + 31589759 = 31590556
863 + 31589693 = 31590556

Showing the first eight; more decompositions exist.
