Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599864, here are decompositions:

5 + 31599859 = 31599864
41 + 31599823 = 31599864
53 + 31599811 = 31599864
83 + 31599781 = 31599864
97 + 31599767 = 31599864
103 + 31599761 = 31599864
137 + 31599727 = 31599864
157 + 31599707 = 31599864

Showing the first eight; more decompositions exist.
