Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566552, here are decompositions:

5 + 31566547 = 31566552
11 + 31566541 = 31566552
29 + 31566523 = 31566552
71 + 31566481 = 31566552
79 + 31566473 = 31566552
103 + 31566449 = 31566552
109 + 31566443 = 31566552
163 + 31566389 = 31566552

Showing the first eight; more decompositions exist.
