Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 586640, here are decompositions:

7 + 586633 = 586640
13 + 586627 = 586640
31 + 586609 = 586640
37 + 586603 = 586640
73 + 586567 = 586640
97 + 586543 = 586640
139 + 586501 = 586640
181 + 586459 = 586640

Showing the first eight; more decompositions exist.
