Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017998, here are decompositions:

109 + 1017889 = 1017998
139 + 1017859 = 1017998
151 + 1017847 = 1017998
181 + 1017817 = 1017998
199 + 1017799 = 1017998
211 + 1017787 = 1017998
277 + 1017721 = 1017998
349 + 1017649 = 1017998

Showing the first eight; more decompositions exist.
