Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600150, here are decompositions:

17 + 31600133 = 31600150
47 + 31600103 = 31600150
89 + 31600061 = 31600150
107 + 31600043 = 31600150
149 + 31600001 = 31600150
173 + 31599977 = 31600150
191 + 31599959 = 31600150
233 + 31599917 = 31600150

Showing the first eight; more decompositions exist.
