Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018926, here are decompositions:

19 + 1018907 = 1018926
23 + 1018903 = 1018926
37 + 1018889 = 1018926
47 + 1018879 = 1018926
53 + 1018873 = 1018926
67 + 1018859 = 1018926
109 + 1018817 = 1018926
113 + 1018813 = 1018926

Showing the first eight; more decompositions exist.
