Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584344, here are decompositions:

7 + 31584337 = 31584344
37 + 31584307 = 31584344
97 + 31584247 = 31584344
151 + 31584193 = 31584344
277 + 31584067 = 31584344
373 + 31583971 = 31584344
433 + 31583911 = 31584344
487 + 31583857 = 31584344

Showing the first eight; more decompositions exist.
