Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029478, here are decompositions:

5 + 1029473 = 1029478
11 + 1029467 = 1029478
71 + 1029407 = 1029478
137 + 1029341 = 1029478
227 + 1029251 = 1029478
269 + 1029209 = 1029478
311 + 1029167 = 1029478
479 + 1028999 = 1029478

Showing the first eight; more decompositions exist.
