Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584856, here are decompositions:

3 + 31584853 = 31584856
47 + 31584809 = 31584856
59 + 31584797 = 31584856
167 + 31584689 = 31584856
239 + 31584617 = 31584856
449 + 31584407 = 31584856
467 + 31584389 = 31584856
557 + 31584299 = 31584856

Showing the first eight; more decompositions exist.
