Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9924, here are decompositions:

17 + 9907 = 9924
23 + 9901 = 9924
37 + 9887 = 9924
41 + 9883 = 9924
53 + 9871 = 9924
67 + 9857 = 9924
73 + 9851 = 9924
107 + 9817 = 9924

Showing the first eight; more decompositions exist.
