Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018954, here are decompositions:

5 + 1018949 = 1018954
17 + 1018937 = 1018954
23 + 1018931 = 1018954
47 + 1018907 = 1018954
137 + 1018817 = 1018954
191 + 1018763 = 1018954
257 + 1018697 = 1018954
281 + 1018673 = 1018954

Showing the first eight; more decompositions exist.
