Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028018, here are decompositions:

7 + 1028011 = 1028018
31 + 1027987 = 1028018
127 + 1027891 = 1028018
241 + 1027777 = 1028018
331 + 1027687 = 1028018
421 + 1027597 = 1028018
499 + 1027519 = 1028018
547 + 1027471 = 1028018

Showing the first eight; more decompositions exist.
