Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023728, here are decompositions:

7 + 1023721 = 1023728
31 + 1023697 = 1023728
127 + 1023601 = 1023728
151 + 1023577 = 1023728
157 + 1023571 = 1023728
229 + 1023499 = 1023728
241 + 1023487 = 1023728
337 + 1023391 = 1023728

Showing the first eight; more decompositions exist.
