Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018998, here are decompositions:

5 + 1018993 = 1018998
11 + 1018987 = 1018998
17 + 1018981 = 1018998
31 + 1018967 = 1018998
41 + 1018957 = 1018998
61 + 1018937 = 1018998
67 + 1018931 = 1018998
109 + 1018889 = 1018998

Showing the first eight; more decompositions exist.
