Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567252, here are decompositions:

11 + 31567241 = 31567252
389 + 31566863 = 31567252
449 + 31566803 = 31567252
503 + 31566749 = 31567252
593 + 31566659 = 31567252
641 + 31566611 = 31567252
653 + 31566599 = 31567252
809 + 31566443 = 31567252

Showing the first eight; more decompositions exist.
