Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006872, here are decompositions:

11 + 1006861 = 1006872
19 + 1006853 = 1006872
73 + 1006799 = 1006872
89 + 1006783 = 1006872
103 + 1006769 = 1006872
151 + 1006721 = 1006872
239 + 1006633 = 1006872
263 + 1006609 = 1006872

Showing the first eight; more decompositions exist.
