Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566576, here are decompositions:

17 + 31566559 = 31566576
29 + 31566547 = 31566576
53 + 31566523 = 31566576
59 + 31566517 = 31566576
79 + 31566497 = 31566576
89 + 31566487 = 31566576
103 + 31566473 = 31566576
127 + 31566449 = 31566576

Showing the first eight; more decompositions exist.
