Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566834, here are decompositions:

7 + 31566827 = 31566834
17 + 31566817 = 31566834
31 + 31566803 = 31566834
37 + 31566797 = 31566834
41 + 31566793 = 31566834
71 + 31566763 = 31566834
97 + 31566737 = 31566834
223 + 31566611 = 31566834

Showing the first eight; more decompositions exist.
