Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018718, here are decompositions:

7 + 1018711 = 1018718
67 + 1018651 = 1018718
97 + 1018621 = 1018718
229 + 1018489 = 1018718
241 + 1018477 = 1018718
271 + 1018447 = 1018718
307 + 1018411 = 1018718
409 + 1018309 = 1018718

Showing the first eight; more decompositions exist.
