Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566024, here are decompositions:

5 + 31566019 = 31566024
11 + 31566013 = 31566024
23 + 31566001 = 31566024
31 + 31565993 = 31566024
43 + 31565981 = 31566024
53 + 31565971 = 31566024
71 + 31565953 = 31566024
107 + 31565917 = 31566024

Showing the first eight; more decompositions exist.
