Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018974, here are decompositions:

7 + 1018967 = 1018974
17 + 1018957 = 1018974
37 + 1018937 = 1018974
43 + 1018931 = 1018974
67 + 1018907 = 1018974
71 + 1018903 = 1018974
101 + 1018873 = 1018974
157 + 1018817 = 1018974

Showing the first eight; more decompositions exist.
