Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038690, here are decompositions:

19 + 1038671 = 1038690
47 + 1038643 = 1038690
53 + 1038637 = 1038690
61 + 1038629 = 1038690
67 + 1038623 = 1038690
71 + 1038619 = 1038690
73 + 1038617 = 1038690
89 + 1038601 = 1038690

Showing the first eight; more decompositions exist.
