Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590448, here are decompositions:

5 + 31590443 = 31590448
47 + 31590401 = 31590448
179 + 31590269 = 31590448
311 + 31590137 = 31590448
359 + 31590089 = 31590448
467 + 31589981 = 31590448
557 + 31589891 = 31590448
587 + 31589861 = 31590448

Showing the first eight; more decompositions exist.
