Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018474, here are decompositions:

3 + 1018471 = 1018474
53 + 1018421 = 1018474
137 + 1018337 = 1018474
173 + 1018301 = 1018474
227 + 1018247 = 1018474
251 + 1018223 = 1018474
257 + 1018217 = 1018474
383 + 1018091 = 1018474

Showing the first eight; more decompositions exist.
