Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567000, here are decompositions:

89 + 31566911 = 31567000
137 + 31566863 = 31567000
173 + 31566827 = 31567000
197 + 31566803 = 31567000
251 + 31566749 = 31567000
263 + 31566737 = 31567000
389 + 31566611 = 31567000
401 + 31566599 = 31567000

Showing the first eight; more decompositions exist.
