Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599960, here are decompositions:

19 + 31599941 = 31599960
31 + 31599929 = 31599960
43 + 31599917 = 31599960
47 + 31599913 = 31599960
59 + 31599901 = 31599960
83 + 31599877 = 31599960
89 + 31599871 = 31599960
101 + 31599859 = 31599960

Showing the first eight; more decompositions exist.
