Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038800, here are decompositions:

3 + 1038797 = 1038800
43 + 1038757 = 1038800
73 + 1038727 = 1038800
79 + 1038721 = 1038800
109 + 1038691 = 1038800
157 + 1038643 = 1038800
163 + 1038637 = 1038800
181 + 1038619 = 1038800

Showing the first eight; more decompositions exist.
