Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580816, here are decompositions:

3 + 580813 = 580816
23 + 580793 = 580816
29 + 580787 = 580816
53 + 580763 = 580816
59 + 580757 = 580816
83 + 580733 = 580816
239 + 580577 = 580816
263 + 580553 = 580816

Showing the first eight; more decompositions exist.
