Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566006, here are decompositions:

5 + 31566001 = 31566006
13 + 31565993 = 31566006
37 + 31565969 = 31566006
53 + 31565953 = 31566006
89 + 31565917 = 31566006
137 + 31565869 = 31566006
293 + 31565713 = 31566006
313 + 31565693 = 31566006

Showing the first eight; more decompositions exist.
