Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023740, here are decompositions:

7 + 1023733 = 1023740
19 + 1023721 = 1023740
43 + 1023697 = 1023740
97 + 1023643 = 1023740
139 + 1023601 = 1023740
163 + 1023577 = 1023740
199 + 1023541 = 1023740
241 + 1023499 = 1023740

Showing the first eight; more decompositions exist.
