Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018688, here are decompositions:

19 + 1018669 = 1018688
37 + 1018651 = 1018688
67 + 1018621 = 1018688
199 + 1018489 = 1018688
211 + 1018477 = 1018688
241 + 1018447 = 1018688
277 + 1018411 = 1018688
331 + 1018357 = 1018688

Showing the first eight; more decompositions exist.
