Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038478, here are decompositions:

29 + 1038449 = 1038478
149 + 1038329 = 1038478
167 + 1038311 = 1038478
227 + 1038251 = 1038478
251 + 1038227 = 1038478
269 + 1038209 = 1038478
359 + 1038119 = 1038478
401 + 1038077 = 1038478

Showing the first eight; more decompositions exist.
