Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567636, here are decompositions:

17 + 31567619 = 31567636
83 + 31567553 = 31567636
239 + 31567397 = 31567636
479 + 31567157 = 31567636
587 + 31567049 = 31567636
593 + 31567043 = 31567636
773 + 31566863 = 31567636
797 + 31566839 = 31567636

Showing the first eight; more decompositions exist.
