Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600006, here are decompositions:

5 + 31600001 = 31600006
29 + 31599977 = 31600006
47 + 31599959 = 31600006
89 + 31599917 = 31600006
197 + 31599809 = 31600006
233 + 31599773 = 31600006
239 + 31599767 = 31600006
353 + 31599653 = 31600006

Showing the first eight; more decompositions exist.
