Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 585840, here are decompositions:

41 + 585799 = 585840
61 + 585779 = 585840
83 + 585757 = 585840
97 + 585743 = 585840
103 + 585737 = 585840
107 + 585733 = 585840
113 + 585727 = 585840
149 + 585691 = 585840

Showing the first eight; more decompositions exist.
