Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477444, here are decompositions:

17 + 31477427 = 31477444
263 + 31477181 = 31477444
281 + 31477163 = 31477444
563 + 31476881 = 31477444
701 + 31476743 = 31477444
821 + 31476623 = 31477444
857 + 31476587 = 31477444
983 + 31476461 = 31477444

Showing the first eight; more decompositions exist.
