Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018066, here are decompositions:

47 + 1018019 = 1018066
59 + 1018007 = 1018066
107 + 1017959 = 1018066
113 + 1017953 = 1018066
239 + 1017827 = 1018066
317 + 1017749 = 1018066
347 + 1017719 = 1018066
353 + 1017713 = 1018066

Showing the first eight; more decompositions exist.
