Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038828, here are decompositions:

5 + 1038823 = 1038828
17 + 1038811 = 1038828
31 + 1038797 = 1038828
71 + 1038757 = 1038828
97 + 1038731 = 1038828
101 + 1038727 = 1038828
107 + 1038721 = 1038828
137 + 1038691 = 1038828

Showing the first eight; more decompositions exist.
