Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533144, here are decompositions:

11 + 31533133 = 31533144
17 + 31533127 = 31533144
43 + 31533101 = 31533144
47 + 31533097 = 31533144
53 + 31533091 = 31533144
131 + 31533013 = 31533144
163 + 31532981 = 31533144
173 + 31532971 = 31533144

Showing the first eight; more decompositions exist.
