Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 579820, here are decompositions:

11 + 579809 = 579820
41 + 579779 = 579820
47 + 579773 = 579820
83 + 579737 = 579820
107 + 579713 = 579820
113 + 579707 = 579820
167 + 579653 = 579820
179 + 579641 = 579820

Showing the first eight; more decompositions exist.
