Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524448, here are decompositions:

29 + 31524419 = 31524448
191 + 31524257 = 31524448
251 + 31524197 = 31524448
281 + 31524167 = 31524448
401 + 31524047 = 31524448
509 + 31523939 = 31524448
647 + 31523801 = 31524448
797 + 31523651 = 31524448

Showing the first eight; more decompositions exist.
