Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11938, here are decompositions:

5 + 11933 = 11938
11 + 11927 = 11938
29 + 11909 = 11938
41 + 11897 = 11938
71 + 11867 = 11938
107 + 11831 = 11938
131 + 11807 = 11938
137 + 11801 = 11938

Showing the first eight; more decompositions exist.
