Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567066, here are decompositions:

17 + 31567049 = 31567066
23 + 31567043 = 31567066
227 + 31566839 = 31567066
239 + 31566827 = 31567066
263 + 31566803 = 31567066
269 + 31566797 = 31567066
317 + 31566749 = 31567066
353 + 31566713 = 31567066

Showing the first eight; more decompositions exist.
