Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584974, here are decompositions:

7 + 31584967 = 31584974
13 + 31584961 = 31584974
67 + 31584907 = 31584974
73 + 31584901 = 31584974
151 + 31584823 = 31584974
271 + 31584703 = 31584974
277 + 31584697 = 31584974
307 + 31584667 = 31584974

Showing the first eight; more decompositions exist.
