Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533132, here are decompositions:

5 + 31533127 = 31533132
13 + 31533119 = 31533132
31 + 31533101 = 31533132
41 + 31533091 = 31533132
131 + 31533001 = 31533132
151 + 31532981 = 31533132
173 + 31532959 = 31533132
193 + 31532939 = 31533132

Showing the first eight; more decompositions exist.
