Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599926, here are decompositions:

13 + 31599913 = 31599926
67 + 31599859 = 31599926
103 + 31599823 = 31599926
199 + 31599727 = 31599926
223 + 31599703 = 31599926
277 + 31599649 = 31599926
373 + 31599553 = 31599926
439 + 31599487 = 31599926

Showing the first eight; more decompositions exist.
