Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018986, here are decompositions:

5 + 1018981 = 1018986
19 + 1018967 = 1018986
29 + 1018957 = 1018986
37 + 1018949 = 1018986
79 + 1018907 = 1018986
83 + 1018903 = 1018986
97 + 1018889 = 1018986
107 + 1018879 = 1018986

Showing the first eight; more decompositions exist.
