Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038740, here are decompositions:

13 + 1038727 = 1038740
19 + 1038721 = 1038740
97 + 1038643 = 1038740
103 + 1038637 = 1038740
139 + 1038601 = 1038740
151 + 1038589 = 1038740
211 + 1038529 = 1038740
277 + 1038463 = 1038740

Showing the first eight; more decompositions exist.
