Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584836, here are decompositions:

7 + 31584829 = 31584836
13 + 31584823 = 31584836
67 + 31584769 = 31584836
79 + 31584757 = 31584836
139 + 31584697 = 31584836
223 + 31584613 = 31584836
229 + 31584607 = 31584836
277 + 31584559 = 31584836

Showing the first eight; more decompositions exist.
