Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517872, here are decompositions:

11 + 517861 = 517872
41 + 517831 = 517872
139 + 517733 = 517872
151 + 517721 = 517872
233 + 517639 = 517872
263 + 517609 = 517872
269 + 517603 = 517872
283 + 517589 = 517872

Showing the first eight; more decompositions exist.
