Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566084, here are decompositions:

5 + 31566079 = 31566084
7 + 31566077 = 31566084
23 + 31566061 = 31566084
41 + 31566043 = 31566084
71 + 31566013 = 31566084
83 + 31566001 = 31566084
103 + 31565981 = 31566084
113 + 31565971 = 31566084

Showing the first eight; more decompositions exist.
