Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566354, here are decompositions:

5 + 31566349 = 31566354
7 + 31566347 = 31566354
37 + 31566317 = 31566354
67 + 31566287 = 31566354
103 + 31566251 = 31566354
107 + 31566247 = 31566354
163 + 31566191 = 31566354
223 + 31566131 = 31566354

Showing the first eight; more decompositions exist.
