Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016872, here are decompositions:

23 + 1016849 = 1016872
29 + 1016843 = 1016872
83 + 1016789 = 1016872
89 + 1016783 = 1016872
191 + 1016681 = 1016872
251 + 1016621 = 1016872
383 + 1016489 = 1016872
419 + 1016453 = 1016872

Showing the first eight; more decompositions exist.
