Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018910, here are decompositions:

3 + 1018907 = 1018910
7 + 1018903 = 1018910
31 + 1018879 = 1018910
37 + 1018873 = 1018910
97 + 1018813 = 1018910
103 + 1018807 = 1018910
181 + 1018729 = 1018910
199 + 1018711 = 1018910

Showing the first eight; more decompositions exist.
