Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533024, here are decompositions:

11 + 31533013 = 31533024
23 + 31533001 = 31533024
43 + 31532981 = 31533024
53 + 31532971 = 31533024
101 + 31532923 = 31533024
151 + 31532873 = 31533024
157 + 31532867 = 31533024
191 + 31532833 = 31533024

Showing the first eight; more decompositions exist.
