Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013278, here are decompositions:

11 + 1013267 = 1013278
29 + 1013249 = 1013278
41 + 1013237 = 1013278
269 + 1013009 = 1013278
281 + 1012997 = 1013278
311 + 1012967 = 1013278
347 + 1012931 = 1013278
359 + 1012919 = 1013278

Showing the first eight; more decompositions exist.
