Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567054, here are decompositions:

5 + 31567049 = 31567054
11 + 31567043 = 31567054
191 + 31566863 = 31567054
227 + 31566827 = 31567054
251 + 31566803 = 31567054
257 + 31566797 = 31567054
317 + 31566737 = 31567054
443 + 31566611 = 31567054

Showing the first eight; more decompositions exist.
