Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584824, here are decompositions:

67 + 31584757 = 31584824
127 + 31584697 = 31584824
157 + 31584667 = 31584824
211 + 31584613 = 31584824
223 + 31584601 = 31584824
277 + 31584547 = 31584824
283 + 31584541 = 31584824
367 + 31584457 = 31584824

Showing the first eight; more decompositions exist.
