Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566896, here are decompositions:

79 + 31566817 = 31566896
103 + 31566793 = 31566896
307 + 31566589 = 31566896
337 + 31566559 = 31566896
349 + 31566547 = 31566896
373 + 31566523 = 31566896
379 + 31566517 = 31566896
409 + 31566487 = 31566896

Showing the first eight; more decompositions exist.
