Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584710, here are decompositions:

7 + 31584703 = 31584710
13 + 31584697 = 31584710
43 + 31584667 = 31584710
97 + 31584613 = 31584710
103 + 31584607 = 31584710
109 + 31584601 = 31584710
151 + 31584559 = 31584710
163 + 31584547 = 31584710

Showing the first eight; more decompositions exist.
