Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10938, here are decompositions:

29 + 10909 = 10938
47 + 10891 = 10938
71 + 10867 = 10938
79 + 10859 = 10938
101 + 10837 = 10938
107 + 10831 = 10938
139 + 10799 = 10938
149 + 10789 = 10938

Showing the first eight; more decompositions exist.
