Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018338, here are decompositions:

29 + 1018309 = 1018338
37 + 1018301 = 1018338
47 + 1018291 = 1018338
67 + 1018271 = 1018338
131 + 1018207 = 1018338
137 + 1018201 = 1018338
229 + 1018109 = 1018338
241 + 1018097 = 1018338

Showing the first eight; more decompositions exist.
