Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038816, here are decompositions:

5 + 1038811 = 1038816
13 + 1038803 = 1038816
19 + 1038797 = 1038816
59 + 1038757 = 1038816
89 + 1038727 = 1038816
109 + 1038707 = 1038816
127 + 1038689 = 1038816
173 + 1038643 = 1038816

Showing the first eight; more decompositions exist.
