Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018536, here are decompositions:

23 + 1018513 = 1018536
47 + 1018489 = 1018536
59 + 1018477 = 1018536
89 + 1018447 = 1018536
97 + 1018439 = 1018536
107 + 1018429 = 1018536
179 + 1018357 = 1018536
199 + 1018337 = 1018536

Showing the first eight; more decompositions exist.
