Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038138, here are decompositions:

11 + 1038127 = 1038138
19 + 1038119 = 1038138
61 + 1038077 = 1038138
97 + 1038041 = 1038138
109 + 1038029 = 1038138
137 + 1038001 = 1038138
181 + 1037957 = 1038138
197 + 1037941 = 1038138

Showing the first eight; more decompositions exist.
