Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019790, here are decompositions:

7 + 1019783 = 1019790
19 + 1019771 = 1019790
43 + 1019747 = 1019790
59 + 1019731 = 1019790
61 + 1019729 = 1019790
67 + 1019723 = 1019790
73 + 1019717 = 1019790
89 + 1019701 = 1019790

Showing the first eight; more decompositions exist.
