Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9564, here are decompositions:

13 + 9551 = 9564
17 + 9547 = 9564
31 + 9533 = 9564
43 + 9521 = 9564
53 + 9511 = 9564
67 + 9497 = 9564
73 + 9491 = 9564
97 + 9467 = 9564

Showing the first eight; more decompositions exist.
