Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584756, here are decompositions:

43 + 31584713 = 31584756
53 + 31584703 = 31584756
59 + 31584697 = 31584756
67 + 31584689 = 31584756
89 + 31584667 = 31584756
103 + 31584653 = 31584756
139 + 31584617 = 31584756
149 + 31584607 = 31584756

Showing the first eight; more decompositions exist.
