Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600048, here are decompositions:

5 + 31600043 = 31600048
47 + 31600001 = 31600048
71 + 31599977 = 31600048
89 + 31599959 = 31600048
107 + 31599941 = 31600048
131 + 31599917 = 31600048
239 + 31599809 = 31600048
281 + 31599767 = 31600048

Showing the first eight; more decompositions exist.
