Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599976, here are decompositions:

17 + 31599959 = 31599976
47 + 31599929 = 31599976
59 + 31599917 = 31599976
167 + 31599809 = 31599976
269 + 31599707 = 31599976
293 + 31599683 = 31599976
347 + 31599629 = 31599976
587 + 31599389 = 31599976

Showing the first eight; more decompositions exist.
