Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566606, here are decompositions:

7 + 31566599 = 31566606
17 + 31566589 = 31566606
47 + 31566559 = 31566606
59 + 31566547 = 31566606
79 + 31566527 = 31566606
83 + 31566523 = 31566606
89 + 31566517 = 31566606
109 + 31566497 = 31566606

Showing the first eight; more decompositions exist.
