Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028776, here are decompositions:

3 + 1028773 = 1028776
29 + 1028747 = 1028776
107 + 1028669 = 1028776
113 + 1028663 = 1028776
179 + 1028597 = 1028776
197 + 1028579 = 1028776
383 + 1028393 = 1028776
443 + 1028333 = 1028776

Showing the first eight; more decompositions exist.
