Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524968, here are decompositions:

31 + 31524937 = 31524968
499 + 31524469 = 31524968
691 + 31524277 = 31524968
877 + 31524091 = 31524968
919 + 31524049 = 31524968
1051 + 31523917 = 31524968
1087 + 31523881 = 31524968
1117 + 31523851 = 31524968

Showing the first eight; more decompositions exist.
