Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477296, here are decompositions:

5 + 31477291 = 31477296
7 + 31477289 = 31477296
83 + 31477213 = 31477296
89 + 31477207 = 31477296
197 + 31477099 = 31477296
229 + 31477067 = 31477296
233 + 31477063 = 31477296
239 + 31477057 = 31477296

Showing the first eight; more decompositions exist.
