Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447484, here are decompositions:

7 + 31447477 = 31447484
43 + 31447441 = 31447484
127 + 31447357 = 31447484
151 + 31447333 = 31447484
457 + 31447027 = 31447484
463 + 31447021 = 31447484
487 + 31446997 = 31447484
547 + 31446937 = 31447484

Showing the first eight; more decompositions exist.
