Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566152, here are decompositions:

73 + 31566079 = 31566152
109 + 31566043 = 31566152
139 + 31566013 = 31566152
151 + 31566001 = 31566152
181 + 31565971 = 31566152
199 + 31565953 = 31566152
223 + 31565929 = 31566152
283 + 31565869 = 31566152

Showing the first eight; more decompositions exist.
