Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584874, here are decompositions:

5 + 31584869 = 31584874
257 + 31584617 = 31584874
443 + 31584431 = 31584874
467 + 31584407 = 31584874
491 + 31584383 = 31584874
593 + 31584281 = 31584874
641 + 31584233 = 31584874
677 + 31584197 = 31584874

Showing the first eight; more decompositions exist.
