Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042638, here are decompositions:

5 + 1042633 = 1042638
7 + 1042631 = 1042638
19 + 1042619 = 1042638
29 + 1042609 = 1042638
31 + 1042607 = 1042638
41 + 1042597 = 1042638
61 + 1042577 = 1042638
67 + 1042571 = 1042638

Showing the first eight; more decompositions exist.
