Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588716, here are decompositions:

7 + 31588709 = 31588716
17 + 31588699 = 31588716
23 + 31588693 = 31588716
37 + 31588679 = 31588716
43 + 31588673 = 31588716
59 + 31588657 = 31588716
73 + 31588643 = 31588716
109 + 31588607 = 31588716

Showing the first eight; more decompositions exist.
