Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599996, here are decompositions:

19 + 31599977 = 31599996
37 + 31599959 = 31599996
67 + 31599929 = 31599996
79 + 31599917 = 31599996
83 + 31599913 = 31599996
137 + 31599859 = 31599996
173 + 31599823 = 31599996
223 + 31599773 = 31599996

Showing the first eight; more decompositions exist.
