Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566334, here are decompositions:

5 + 31566329 = 31566334
17 + 31566317 = 31566334
47 + 31566287 = 31566334
83 + 31566251 = 31566334
113 + 31566221 = 31566334
167 + 31566167 = 31566334
197 + 31566137 = 31566334
251 + 31566083 = 31566334

Showing the first eight; more decompositions exist.
