Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9930, here are decompositions:

7 + 9923 = 9930
23 + 9907 = 9930
29 + 9901 = 9930
43 + 9887 = 9930
47 + 9883 = 9930
59 + 9871 = 9930
71 + 9859 = 9930
73 + 9857 = 9930

Showing the first eight; more decompositions exist.
