Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016278, here are decompositions:

41 + 1016237 = 1016278
47 + 1016231 = 1016278
167 + 1016111 = 1016278
227 + 1016051 = 1016278
251 + 1016027 = 1016278
269 + 1016009 = 1016278
311 + 1015967 = 1016278
359 + 1015919 = 1016278

Showing the first eight; more decompositions exist.
