Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9540, here are decompositions:

7 + 9533 = 9540
19 + 9521 = 9540
29 + 9511 = 9540
43 + 9497 = 9540
61 + 9479 = 9540
67 + 9473 = 9540
73 + 9467 = 9540
79 + 9461 = 9540

Showing the first eight; more decompositions exist.
