Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038738, here are decompositions:

7 + 1038731 = 1038738
11 + 1038727 = 1038738
17 + 1038721 = 1038738
31 + 1038707 = 1038738
47 + 1038691 = 1038738
67 + 1038671 = 1038738
101 + 1038637 = 1038738
109 + 1038629 = 1038738

Showing the first eight; more decompositions exist.
