Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1053728, here are decompositions:

31 + 1053697 = 1053728
37 + 1053691 = 1053728
139 + 1053589 = 1053728
157 + 1053571 = 1053728
199 + 1053529 = 1053728
241 + 1053487 = 1053728
307 + 1053421 = 1053728
367 + 1053361 = 1053728

Showing the first eight; more decompositions exist.
