Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017838, here are decompositions:

11 + 1017827 = 1017838
89 + 1017749 = 1017838
191 + 1017647 = 1017838
359 + 1017479 = 1017838
389 + 1017449 = 1017838
401 + 1017437 = 1017838
461 + 1017377 = 1017838
467 + 1017371 = 1017838

Showing the first eight; more decompositions exist.
