Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 585808, here are decompositions:

17 + 585791 = 585808
29 + 585779 = 585808
59 + 585749 = 585808
71 + 585737 = 585808
131 + 585677 = 585808
137 + 585671 = 585808
227 + 585581 = 585808
239 + 585569 = 585808

Showing the first eight; more decompositions exist.
