Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019740, here are decompositions:

11 + 1019729 = 1019740
17 + 1019723 = 1019740
23 + 1019717 = 1019740
41 + 1019699 = 1019740
47 + 1019693 = 1019740
53 + 1019687 = 1019740
83 + 1019657 = 1019740
101 + 1019639 = 1019740

Showing the first eight; more decompositions exist.
