Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584708, here are decompositions:

5 + 31584703 = 31584708
11 + 31584697 = 31584708
19 + 31584689 = 31584708
41 + 31584667 = 31584708
101 + 31584607 = 31584708
107 + 31584601 = 31584708
131 + 31584577 = 31584708
149 + 31584559 = 31584708

Showing the first eight; more decompositions exist.
