Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019730, here are decompositions:

7 + 1019723 = 1019730
13 + 1019717 = 1019730
17 + 1019713 = 1019730
29 + 1019701 = 1019730
31 + 1019699 = 1019730
37 + 1019693 = 1019730
43 + 1019687 = 1019730
67 + 1019663 = 1019730

Showing the first eight; more decompositions exist.
