Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002788, here are decompositions:

19 + 1002769 = 1002788
37 + 1002751 = 1002788
67 + 1002721 = 1002788
79 + 1002709 = 1002788
109 + 1002679 = 1002788
211 + 1002577 = 1002788
271 + 1002517 = 1002788
277 + 1002511 = 1002788

Showing the first eight; more decompositions exist.
