Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038216, here are decompositions:

5 + 1038211 = 1038216
7 + 1038209 = 1038216
13 + 1038203 = 1038216
17 + 1038199 = 1038216
29 + 1038187 = 1038216
59 + 1038157 = 1038216
73 + 1038143 = 1038216
89 + 1038127 = 1038216

Showing the first eight; more decompositions exist.
