Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008478, here are decompositions:

11 + 1008467 = 1008478
41 + 1008437 = 1008478
59 + 1008419 = 1008478
71 + 1008407 = 1008478
131 + 1008347 = 1008478
239 + 1008239 = 1008478
269 + 1008209 = 1008478
347 + 1008131 = 1008478

Showing the first eight; more decompositions exist.
