Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524562, here are decompositions:

29 + 31524533 = 31524562
53 + 31524509 = 31524562
269 + 31524293 = 31524562
401 + 31524161 = 31524562
761 + 31523801 = 31524562
809 + 31523753 = 31524562
911 + 31523651 = 31524562
929 + 31523633 = 31524562

Showing the first eight; more decompositions exist.
