Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018678, here are decompositions:

5 + 1018673 = 1018678
29 + 1018649 = 1018678
239 + 1018439 = 1018678
257 + 1018421 = 1018678
431 + 1018247 = 1018678
461 + 1018217 = 1018678
569 + 1018109 = 1018678
587 + 1018091 = 1018678

Showing the first eight; more decompositions exist.
