Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584704, here are decompositions:

7 + 31584697 = 31584704
37 + 31584667 = 31584704
97 + 31584607 = 31584704
103 + 31584601 = 31584704
127 + 31584577 = 31584704
157 + 31584547 = 31584704
163 + 31584541 = 31584704
181 + 31584523 = 31584704

Showing the first eight; more decompositions exist.
