Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533152, here are decompositions:

3 + 31533149 = 31533152
19 + 31533133 = 31533152
61 + 31533091 = 31533152
139 + 31533013 = 31533152
151 + 31533001 = 31533152
181 + 31532971 = 31533152
193 + 31532959 = 31533152
229 + 31532923 = 31533152

Showing the first eight; more decompositions exist.
