Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566934, here are decompositions:

23 + 31566911 = 31566934
71 + 31566863 = 31566934
107 + 31566827 = 31566934
131 + 31566803 = 31566934
137 + 31566797 = 31566934
197 + 31566737 = 31566934
461 + 31566473 = 31566934
491 + 31566443 = 31566934

Showing the first eight; more decompositions exist.
