Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018668, here are decompositions:

17 + 1018651 = 1018668
19 + 1018649 = 1018668
47 + 1018621 = 1018668
109 + 1018559 = 1018668
179 + 1018489 = 1018668
191 + 1018477 = 1018668
197 + 1018471 = 1018668
229 + 1018439 = 1018668

Showing the first eight; more decompositions exist.
