Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566014, here are decompositions:

13 + 31566001 = 31566014
43 + 31565971 = 31566014
61 + 31565953 = 31566014
97 + 31565917 = 31566014
127 + 31565887 = 31566014
163 + 31565851 = 31566014
211 + 31565803 = 31566014
223 + 31565791 = 31566014

Showing the first eight; more decompositions exist.
