Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027998, here are decompositions:

11 + 1027987 = 1027998
29 + 1027969 = 1027998
67 + 1027931 = 1027998
107 + 1027891 = 1027998
157 + 1027841 = 1027998
199 + 1027799 = 1027998
211 + 1027787 = 1027998
239 + 1027759 = 1027998

Showing the first eight; more decompositions exist.
