Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016878, here are decompositions:

29 + 1016849 = 1016878
89 + 1016789 = 1016878
101 + 1016777 = 1016878
197 + 1016681 = 1016878
257 + 1016621 = 1016878
281 + 1016597 = 1016878
311 + 1016567 = 1016878
389 + 1016489 = 1016878

Showing the first eight; more decompositions exist.
