Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566294, here are decompositions:

5 + 31566289 = 31566294
7 + 31566287 = 31566294
43 + 31566251 = 31566294
47 + 31566247 = 31566294
73 + 31566221 = 31566294
103 + 31566191 = 31566294
127 + 31566167 = 31566294
157 + 31566137 = 31566294

Showing the first eight; more decompositions exist.
