Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600056, here are decompositions:

13 + 31600043 = 31600056
17 + 31600039 = 31600056
79 + 31599977 = 31600056
97 + 31599959 = 31600056
127 + 31599929 = 31600056
139 + 31599917 = 31600056
179 + 31599877 = 31600056
197 + 31599859 = 31600056

Showing the first eight; more decompositions exist.
