Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9558, here are decompositions:

7 + 9551 = 9558
11 + 9547 = 9558
19 + 9539 = 9558
37 + 9521 = 9558
47 + 9511 = 9558
61 + 9497 = 9558
67 + 9491 = 9558
79 + 9479 = 9558

Showing the first eight; more decompositions exist.
