Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018528, here are decompositions:

89 + 1018439 = 1018528
107 + 1018421 = 1018528
191 + 1018337 = 1018528
227 + 1018301 = 1018528
257 + 1018271 = 1018528
281 + 1018247 = 1018528
311 + 1018217 = 1018528
419 + 1018109 = 1018528

Showing the first eight; more decompositions exist.
