Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031518, here are decompositions:

11 + 1031507 = 1031518
29 + 1031489 = 1031518
41 + 1031477 = 1031518
71 + 1031447 = 1031518
107 + 1031411 = 1031518
227 + 1031291 = 1031518
239 + 1031279 = 1031518
251 + 1031267 = 1031518

Showing the first eight; more decompositions exist.
