Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042740, here are decompositions:

7 + 1042733 = 1042740
31 + 1042709 = 1042740
37 + 1042703 = 1042740
47 + 1042693 = 1042740
53 + 1042687 = 1042740
59 + 1042681 = 1042740
107 + 1042633 = 1042740
109 + 1042631 = 1042740

Showing the first eight; more decompositions exist.
