Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584966, here are decompositions:

5 + 31584961 = 31584966
13 + 31584953 = 31584966
19 + 31584947 = 31584966
59 + 31584907 = 31584966
79 + 31584887 = 31584966
97 + 31584869 = 31584966
113 + 31584853 = 31584966
137 + 31584829 = 31584966

Showing the first eight; more decompositions exist.
