Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016638, here are decompositions:

17 + 1016621 = 1016638
41 + 1016597 = 1016638
71 + 1016567 = 1016638
149 + 1016489 = 1016638
197 + 1016441 = 1016638
239 + 1016399 = 1016638
281 + 1016357 = 1016638
401 + 1016237 = 1016638

Showing the first eight; more decompositions exist.
