Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018654, here are decompositions:

3 + 1018651 = 1018654
5 + 1018649 = 1018654
11 + 1018643 = 1018654
41 + 1018613 = 1018654
71 + 1018583 = 1018654
233 + 1018421 = 1018654
317 + 1018337 = 1018654
353 + 1018301 = 1018654

Showing the first eight; more decompositions exist.
