Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599834, here are decompositions:

11 + 31599823 = 31599834
23 + 31599811 = 31599834
53 + 31599781 = 31599834
61 + 31599773 = 31599834
67 + 31599767 = 31599834
73 + 31599761 = 31599834
107 + 31599727 = 31599834
127 + 31599707 = 31599834

Showing the first eight; more decompositions exist.
