Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018966, here are decompositions:

17 + 1018949 = 1018966
29 + 1018937 = 1018966
59 + 1018907 = 1018966
107 + 1018859 = 1018966
149 + 1018817 = 1018966
197 + 1018769 = 1018966
233 + 1018733 = 1018966
257 + 1018709 = 1018966

Showing the first eight; more decompositions exist.
