Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533090, here are decompositions:

89 + 31533001 = 31533090
109 + 31532981 = 31533090
131 + 31532959 = 31533090
151 + 31532939 = 31533090
167 + 31532923 = 31533090
191 + 31532899 = 31533090
223 + 31532867 = 31533090
227 + 31532863 = 31533090

Showing the first eight; more decompositions exist.
