Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013938, here are decompositions:

5 + 1013933 = 1013938
17 + 1013921 = 1013938
47 + 1013891 = 1013938
59 + 1013879 = 1013938
197 + 1013741 = 1013938
227 + 1013711 = 1013938
239 + 1013699 = 1013938
251 + 1013687 = 1013938

Showing the first eight; more decompositions exist.
