Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584734, here are decompositions:

31 + 31584703 = 31584734
37 + 31584697 = 31584734
67 + 31584667 = 31584734
127 + 31584607 = 31584734
157 + 31584577 = 31584734
193 + 31584541 = 31584734
211 + 31584523 = 31584734
277 + 31584457 = 31584734

Showing the first eight; more decompositions exist.
