Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477332, here are decompositions:

11 + 31477321 = 31477332
31 + 31477301 = 31477332
41 + 31477291 = 31477332
43 + 31477289 = 31477332
151 + 31477181 = 31477332
191 + 31477141 = 31477332
233 + 31477099 = 31477332
269 + 31477063 = 31477332

Showing the first eight; more decompositions exist.
