Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584726, here are decompositions:

13 + 31584713 = 31584726
23 + 31584703 = 31584726
29 + 31584697 = 31584726
37 + 31584689 = 31584726
59 + 31584667 = 31584726
73 + 31584653 = 31584726
109 + 31584617 = 31584726
113 + 31584613 = 31584726

Showing the first eight; more decompositions exist.
