Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000872, here are decompositions:

11 + 1000861 = 1000872
13 + 1000859 = 1000872
23 + 1000849 = 1000872
43 + 1000829 = 1000872
79 + 1000793 = 1000872
109 + 1000763 = 1000872
149 + 1000723 = 1000872
151 + 1000721 = 1000872

Showing the first eight; more decompositions exist.
