Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566944, here are decompositions:

43 + 31566901 = 31566944
127 + 31566817 = 31566944
151 + 31566793 = 31566944
181 + 31566763 = 31566944
313 + 31566631 = 31566944
397 + 31566547 = 31566944
421 + 31566523 = 31566944
457 + 31566487 = 31566944

Showing the first eight; more decompositions exist.
