Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567556, here are decompositions:

3 + 31567553 = 31567556
43 + 31567513 = 31567556
127 + 31567429 = 31567556
277 + 31567279 = 31567556
337 + 31567219 = 31567556
577 + 31566979 = 31567556
739 + 31566817 = 31567556
967 + 31566589 = 31567556

Showing the first eight; more decompositions exist.
