Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8938, here are decompositions:

5 + 8933 = 8938
71 + 8867 = 8938
89 + 8849 = 8938
101 + 8837 = 8938
107 + 8831 = 8938
131 + 8807 = 8938
191 + 8747 = 8938
197 + 8741 = 8938

Showing the first eight; more decompositions exist.
