Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599856, here are decompositions:

47 + 31599809 = 31599856
83 + 31599773 = 31599856
89 + 31599767 = 31599856
149 + 31599707 = 31599856
173 + 31599683 = 31599856
227 + 31599629 = 31599856
257 + 31599599 = 31599856
293 + 31599563 = 31599856

Showing the first eight; more decompositions exist.
