Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599924, here are decompositions:

7 + 31599917 = 31599924
11 + 31599913 = 31599924
23 + 31599901 = 31599924
47 + 31599877 = 31599924
53 + 31599871 = 31599924
101 + 31599823 = 31599924
113 + 31599811 = 31599924
151 + 31599773 = 31599924

Showing the first eight; more decompositions exist.
