Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599930, here are decompositions:

13 + 31599917 = 31599930
17 + 31599913 = 31599930
29 + 31599901 = 31599930
53 + 31599877 = 31599930
59 + 31599871 = 31599930
71 + 31599859 = 31599930
107 + 31599823 = 31599930
149 + 31599781 = 31599930

Showing the first eight; more decompositions exist.
