Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027740, here are decompositions:

13 + 1027727 = 1027740
23 + 1027717 = 1027740
37 + 1027703 = 1027740
47 + 1027693 = 1027740
53 + 1027687 = 1027740
61 + 1027679 = 1027740
97 + 1027643 = 1027740
127 + 1027613 = 1027740

Showing the first eight; more decompositions exist.
