Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038742, here are decompositions:

11 + 1038731 = 1038742
53 + 1038689 = 1038742
71 + 1038671 = 1038742
113 + 1038629 = 1038742
179 + 1038563 = 1038742
239 + 1038503 = 1038742
293 + 1038449 = 1038742
359 + 1038383 = 1038742

Showing the first eight; more decompositions exist.
