Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592016, here are decompositions:

17 + 31591999 = 31592016
19 + 31591997 = 31592016
23 + 31591993 = 31592016
37 + 31591979 = 31592016
59 + 31591957 = 31592016
103 + 31591913 = 31592016
107 + 31591909 = 31592016
149 + 31591867 = 31592016

Showing the first eight; more decompositions exist.
