Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584684, here are decompositions:

17 + 31584667 = 31584684
31 + 31584653 = 31584684
67 + 31584617 = 31584684
71 + 31584613 = 31584684
83 + 31584601 = 31584684
107 + 31584577 = 31584684
137 + 31584547 = 31584684
227 + 31584457 = 31584684

Showing the first eight; more decompositions exist.
