Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477494, here are decompositions:

11 + 31477483 = 31477494
47 + 31477447 = 31477494
67 + 31477427 = 31477494
71 + 31477423 = 31477494
173 + 31477321 = 31477494
193 + 31477301 = 31477494
281 + 31477213 = 31477494
313 + 31477181 = 31477494

Showing the first eight; more decompositions exist.
