Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566342, here are decompositions:

13 + 31566329 = 31566342
43 + 31566299 = 31566342
53 + 31566289 = 31566342
151 + 31566191 = 31566342
173 + 31566169 = 31566342
191 + 31566151 = 31566342
211 + 31566131 = 31566342
263 + 31566079 = 31566342

Showing the first eight; more decompositions exist.
