Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019776, here are decompositions:

5 + 1019771 = 1019776
29 + 1019747 = 1019776
47 + 1019729 = 1019776
53 + 1019723 = 1019776
59 + 1019717 = 1019776
83 + 1019693 = 1019776
89 + 1019687 = 1019776
113 + 1019663 = 1019776

Showing the first eight; more decompositions exist.
