Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 585820, here are decompositions:

29 + 585791 = 585820
41 + 585779 = 585820
71 + 585749 = 585820
83 + 585737 = 585820
149 + 585671 = 585820
167 + 585653 = 585820
227 + 585593 = 585820
233 + 585587 = 585820

Showing the first eight; more decompositions exist.
