Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566182, here are decompositions:

13 + 31566169 = 31566182
31 + 31566151 = 31566182
103 + 31566079 = 31566182
139 + 31566043 = 31566182
163 + 31566019 = 31566182
181 + 31566001 = 31566182
211 + 31565971 = 31566182
229 + 31565953 = 31566182

Showing the first eight; more decompositions exist.
