Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590676, here are decompositions:

17 + 31590659 = 31590676
59 + 31590617 = 31590676
83 + 31590593 = 31590676
197 + 31590479 = 31590676
233 + 31590443 = 31590676
263 + 31590413 = 31590676
587 + 31590089 = 31590676
809 + 31589867 = 31590676

Showing the first eight; more decompositions exist.
