Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477474, here are decompositions:

47 + 31477427 = 31477474
173 + 31477301 = 31477474
293 + 31477181 = 31477474
311 + 31477163 = 31477474
557 + 31476917 = 31477474
593 + 31476881 = 31477474
653 + 31476821 = 31477474
863 + 31476611 = 31477474

Showing the first eight; more decompositions exist.
