Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020728, here are decompositions:

19 + 1020709 = 1020728
61 + 1020667 = 1020728
97 + 1020631 = 1020728
109 + 1020619 = 1020728
139 + 1020589 = 1020728
199 + 1020529 = 1020728
211 + 1020517 = 1020728
271 + 1020457 = 1020728

Showing the first eight; more decompositions exist.
