Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019788, here are decompositions:

5 + 1019783 = 1019788
17 + 1019771 = 1019788
41 + 1019747 = 1019788
47 + 1019741 = 1019788
59 + 1019729 = 1019788
71 + 1019717 = 1019788
89 + 1019699 = 1019788
101 + 1019687 = 1019788

Showing the first eight; more decompositions exist.
