Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584696, here are decompositions:

7 + 31584689 = 31584696
29 + 31584667 = 31584696
43 + 31584653 = 31584696
79 + 31584617 = 31584696
83 + 31584613 = 31584696
89 + 31584607 = 31584696
137 + 31584559 = 31584696
149 + 31584547 = 31584696

Showing the first eight; more decompositions exist.
