Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9960, here are decompositions:

11 + 9949 = 9960
19 + 9941 = 9960
29 + 9931 = 9960
31 + 9929 = 9960
37 + 9923 = 9960
53 + 9907 = 9960
59 + 9901 = 9960
73 + 9887 = 9960

Showing the first eight; more decompositions exist.
