Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584674, here are decompositions:

7 + 31584667 = 31584674
61 + 31584613 = 31584674
67 + 31584607 = 31584674
73 + 31584601 = 31584674
97 + 31584577 = 31584674
127 + 31584547 = 31584674
151 + 31584523 = 31584674
193 + 31584481 = 31584674

Showing the first eight; more decompositions exist.
