Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018554, here are decompositions:

11 + 1018543 = 1018554
41 + 1018513 = 1018554
83 + 1018471 = 1018554
107 + 1018447 = 1018554
197 + 1018357 = 1018554
241 + 1018313 = 1018554
263 + 1018291 = 1018554
283 + 1018271 = 1018554

Showing the first eight; more decompositions exist.
