Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029728, here are decompositions:

31 + 1029697 = 1029728
127 + 1029601 = 1029728
151 + 1029577 = 1029728
181 + 1029547 = 1029728
211 + 1029517 = 1029728
229 + 1029499 = 1029728
241 + 1029487 = 1029728
367 + 1029361 = 1029728

Showing the first eight; more decompositions exist.
