Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477484, here are decompositions:

37 + 31477447 = 31477484
61 + 31477423 = 31477484
163 + 31477321 = 31477484
193 + 31477291 = 31477484
271 + 31477213 = 31477484
277 + 31477207 = 31477484
373 + 31477111 = 31477484
421 + 31477063 = 31477484

Showing the first eight; more decompositions exist.
