Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567306, here are decompositions:

149 + 31567157 = 31567306
257 + 31567049 = 31567306
263 + 31567043 = 31567306
443 + 31566863 = 31567306
467 + 31566839 = 31567306
479 + 31566827 = 31567306
503 + 31566803 = 31567306
509 + 31566797 = 31567306

Showing the first eight; more decompositions exist.
