Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027868, here are decompositions:

109 + 1027759 = 1027868
151 + 1027717 = 1027868
181 + 1027687 = 1027868
271 + 1027597 = 1027868
277 + 1027591 = 1027868
349 + 1027519 = 1027868
379 + 1027489 = 1027868
397 + 1027471 = 1027868

Showing the first eight; more decompositions exist.
