Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026478, here are decompositions:

29 + 1026449 = 1026478
71 + 1026407 = 1026478
107 + 1026371 = 1026478
179 + 1026299 = 1026478
227 + 1026251 = 1026478
251 + 1026227 = 1026478
281 + 1026197 = 1026478
311 + 1026167 = 1026478

Showing the first eight; more decompositions exist.
