Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018458, here are decompositions:

11 + 1018447 = 1018458
19 + 1018439 = 1018458
29 + 1018429 = 1018458
37 + 1018421 = 1018458
47 + 1018411 = 1018458
101 + 1018357 = 1018458
149 + 1018309 = 1018458
157 + 1018301 = 1018458

Showing the first eight; more decompositions exist.
