Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003938, here are decompositions:

7 + 1003931 = 1003938
29 + 1003909 = 1003938
31 + 1003907 = 1003938
41 + 1003897 = 1003938
59 + 1003879 = 1003938
97 + 1003841 = 1003938
151 + 1003787 = 1003938
167 + 1003771 = 1003938

Showing the first eight; more decompositions exist.
