Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 582820, here are decompositions:

11 + 582809 = 582820
47 + 582773 = 582820
53 + 582767 = 582820
59 + 582761 = 582820
83 + 582737 = 582820
89 + 582731 = 582820
101 + 582719 = 582820
131 + 582689 = 582820

Showing the first eight; more decompositions exist.
