Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600198, here are decompositions:

5 + 31600193 = 31600198
41 + 31600157 = 31600198
137 + 31600061 = 31600198
197 + 31600001 = 31600198
239 + 31599959 = 31600198
257 + 31599941 = 31600198
269 + 31599929 = 31600198
281 + 31599917 = 31600198

Showing the first eight; more decompositions exist.
