Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012666, here are decompositions:

3 + 1012663 = 1012666
29 + 1012637 = 1012666
47 + 1012619 = 1012666
107 + 1012559 = 1012666
227 + 1012439 = 1012666
233 + 1012433 = 1012666
269 + 1012397 = 1012666
293 + 1012373 = 1012666

Showing the first eight; more decompositions exist.
