Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567048, here are decompositions:

5 + 31567043 = 31567048
137 + 31566911 = 31567048
251 + 31566797 = 31567048
311 + 31566737 = 31567048
389 + 31566659 = 31567048
449 + 31566599 = 31567048
521 + 31566527 = 31567048
599 + 31566449 = 31567048

Showing the first eight; more decompositions exist.
