Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9942, here are decompositions:

11 + 9931 = 9942
13 + 9929 = 9942
19 + 9923 = 9942
41 + 9901 = 9942
59 + 9883 = 9942
71 + 9871 = 9942
83 + 9859 = 9942
103 + 9839 = 9942

Showing the first eight; more decompositions exist.
