Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024740, here are decompositions:

11 + 1024729 = 1024740
19 + 1024721 = 1024740
29 + 1024711 = 1024740
37 + 1024703 = 1024740
43 + 1024697 = 1024740
47 + 1024693 = 1024740
71 + 1024669 = 1024740
107 + 1024633 = 1024740

Showing the first eight; more decompositions exist.
