Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584834, here are decompositions:

5 + 31584829 = 31584834
11 + 31584823 = 31584834
37 + 31584797 = 31584834
131 + 31584703 = 31584834
137 + 31584697 = 31584834
167 + 31584667 = 31584834
181 + 31584653 = 31584834
227 + 31584607 = 31584834

Showing the first eight; more decompositions exist.
