Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567006, here are decompositions:

167 + 31566839 = 31567006
179 + 31566827 = 31567006
257 + 31566749 = 31567006
269 + 31566737 = 31567006
293 + 31566713 = 31567006
347 + 31566659 = 31567006
479 + 31566527 = 31567006
509 + 31566497 = 31567006

Showing the first eight; more decompositions exist.
