Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018618, here are decompositions:

5 + 1018613 = 1018618
59 + 1018559 = 1018618
179 + 1018439 = 1018618
197 + 1018421 = 1018618
281 + 1018337 = 1018618
317 + 1018301 = 1018618
347 + 1018271 = 1018618
401 + 1018217 = 1018618

Showing the first eight; more decompositions exist.
