Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584716, here are decompositions:

3 + 31584713 = 31584716
13 + 31584703 = 31584716
19 + 31584697 = 31584716
103 + 31584613 = 31584716
109 + 31584607 = 31584716
139 + 31584577 = 31584716
157 + 31584559 = 31584716
193 + 31584523 = 31584716

Showing the first eight; more decompositions exist.
