Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566852, here are decompositions:

13 + 31566839 = 31566852
59 + 31566793 = 31566852
89 + 31566763 = 31566852
103 + 31566749 = 31566852
139 + 31566713 = 31566852
193 + 31566659 = 31566852
241 + 31566611 = 31566852
263 + 31566589 = 31566852

Showing the first eight; more decompositions exist.
