Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047872, here are decompositions:

13 + 1047859 = 1047872
31 + 1047841 = 1047872
109 + 1047763 = 1047872
151 + 1047721 = 1047872
181 + 1047691 = 1047872
223 + 1047649 = 1047872
283 + 1047589 = 1047872
313 + 1047559 = 1047872

Showing the first eight; more decompositions exist.
