Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599896, here are decompositions:

19 + 31599877 = 31599896
37 + 31599859 = 31599896
73 + 31599823 = 31599896
193 + 31599703 = 31599896
397 + 31599499 = 31599896
409 + 31599487 = 31599896
457 + 31599439 = 31599896
547 + 31599349 = 31599896

Showing the first eight; more decompositions exist.
