Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584804, here are decompositions:

7 + 31584797 = 31584804
47 + 31584757 = 31584804
101 + 31584703 = 31584804
107 + 31584697 = 31584804
137 + 31584667 = 31584804
151 + 31584653 = 31584804
191 + 31584613 = 31584804
197 + 31584607 = 31584804

Showing the first eight; more decompositions exist.
