Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018366, here are decompositions:

29 + 1018337 = 1018366
53 + 1018313 = 1018366
113 + 1018253 = 1018366
149 + 1018217 = 1018366
257 + 1018109 = 1018366
269 + 1018097 = 1018366
347 + 1018019 = 1018366
359 + 1018007 = 1018366

Showing the first eight; more decompositions exist.
