Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566594, here are decompositions:

5 + 31566589 = 31566594
47 + 31566547 = 31566594
53 + 31566541 = 31566594
67 + 31566527 = 31566594
71 + 31566523 = 31566594
97 + 31566497 = 31566594
107 + 31566487 = 31566594
113 + 31566481 = 31566594

Showing the first eight; more decompositions exist.
