Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566932, here are decompositions:

13 + 31566919 = 31566932
31 + 31566901 = 31566932
139 + 31566793 = 31566932
223 + 31566709 = 31566932
373 + 31566559 = 31566932
409 + 31566523 = 31566932
643 + 31566289 = 31566932
853 + 31566079 = 31566932

Showing the first eight; more decompositions exist.
