Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 585828, here are decompositions:

29 + 585799 = 585828
37 + 585791 = 585828
71 + 585757 = 585828
79 + 585749 = 585828
101 + 585727 = 585828
107 + 585721 = 585828
137 + 585691 = 585828
151 + 585677 = 585828

Showing the first eight; more decompositions exist.
