Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018950, here are decompositions:

13 + 1018937 = 1018950
19 + 1018931 = 1018950
43 + 1018907 = 1018950
47 + 1018903 = 1018950
61 + 1018889 = 1018950
71 + 1018879 = 1018950
137 + 1018813 = 1018950
139 + 1018811 = 1018950

Showing the first eight; more decompositions exist.
