Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533048, here are decompositions:

47 + 31533001 = 31533048
67 + 31532981 = 31533048
89 + 31532959 = 31533048
109 + 31532939 = 31533048
149 + 31532899 = 31533048
167 + 31532881 = 31533048
181 + 31532867 = 31533048
271 + 31532777 = 31533048

Showing the first eight; more decompositions exist.
