Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027788, here are decompositions:

5 + 1027783 = 1027788
11 + 1027777 = 1027788
29 + 1027759 = 1027788
31 + 1027757 = 1027788
37 + 1027751 = 1027788
61 + 1027727 = 1027788
71 + 1027717 = 1027788
101 + 1027687 = 1027788

Showing the first eight; more decompositions exist.
