Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019728, here are decompositions:

5 + 1019723 = 1019728
11 + 1019717 = 1019728
29 + 1019699 = 1019728
41 + 1019687 = 1019728
71 + 1019657 = 1019728
89 + 1019639 = 1019728
179 + 1019549 = 1019728
191 + 1019537 = 1019728

Showing the first eight; more decompositions exist.
