Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018426, here are decompositions:

5 + 1018421 = 1018426
89 + 1018337 = 1018426
113 + 1018313 = 1018426
173 + 1018253 = 1018426
179 + 1018247 = 1018426
317 + 1018109 = 1018426
419 + 1018007 = 1018426
467 + 1017959 = 1018426

Showing the first eight; more decompositions exist.
