Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049872, here are decompositions:

11 + 1049861 = 1049872
23 + 1049849 = 1049872
29 + 1049843 = 1049872
191 + 1049681 = 1049872
233 + 1049639 = 1049872
269 + 1049603 = 1049872
353 + 1049519 = 1049872
389 + 1049483 = 1049872

Showing the first eight; more decompositions exist.
