Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584914, here are decompositions:

7 + 31584907 = 31584914
13 + 31584901 = 31584914
61 + 31584853 = 31584914
157 + 31584757 = 31584914
211 + 31584703 = 31584914
307 + 31584607 = 31584914
313 + 31584601 = 31584914
337 + 31584577 = 31584914

Showing the first eight; more decompositions exist.
