Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9938, here are decompositions:

7 + 9931 = 9938
31 + 9907 = 9938
37 + 9901 = 9938
67 + 9871 = 9938
79 + 9859 = 9938
109 + 9829 = 9938
127 + 9811 = 9938
151 + 9787 = 9938

Showing the first eight; more decompositions exist.
