Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600066, here are decompositions:

5 + 31600061 = 31600066
23 + 31600043 = 31600066
89 + 31599977 = 31600066
107 + 31599959 = 31600066
137 + 31599929 = 31600066
149 + 31599917 = 31600066
257 + 31599809 = 31600066
293 + 31599773 = 31600066

Showing the first eight; more decompositions exist.
