Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030728, here are decompositions:

5 + 1030723 = 1030728
47 + 1030681 = 1030728
89 + 1030639 = 1030728
109 + 1030619 = 1030728
157 + 1030571 = 1030728
191 + 1030537 = 1030728
199 + 1030529 = 1030728
277 + 1030451 = 1030728

Showing the first eight; more decompositions exist.
