Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038490, here are decompositions:

3 + 1038487 = 1038490
41 + 1038449 = 1038490
107 + 1038383 = 1038490
179 + 1038311 = 1038490
227 + 1038263 = 1038490
239 + 1038251 = 1038490
263 + 1038227 = 1038490
281 + 1038209 = 1038490

Showing the first eight; more decompositions exist.
