Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600270, here are decompositions:

11 + 31600259 = 31600270
113 + 31600157 = 31600270
137 + 31600133 = 31600270
167 + 31600103 = 31600270
227 + 31600043 = 31600270
269 + 31600001 = 31600270
293 + 31599977 = 31600270
311 + 31599959 = 31600270

Showing the first eight; more decompositions exist.
