Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023800, here are decompositions:

31 + 1023769 = 1023800
67 + 1023733 = 1023800
79 + 1023721 = 1023800
103 + 1023697 = 1023800
157 + 1023643 = 1023800
199 + 1023601 = 1023800
223 + 1023577 = 1023800
229 + 1023571 = 1023800

Showing the first eight; more decompositions exist.
