Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018556, here are decompositions:

13 + 1018543 = 1018556
43 + 1018513 = 1018556
67 + 1018489 = 1018556
79 + 1018477 = 1018556
109 + 1018447 = 1018556
127 + 1018429 = 1018556
199 + 1018357 = 1018556
349 + 1018207 = 1018556

Showing the first eight; more decompositions exist.
