Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580720, here are decompositions:

3 + 580717 = 580720
29 + 580691 = 580720
47 + 580673 = 580720
89 + 580631 = 580720
113 + 580607 = 580720
167 + 580553 = 580720
191 + 580529 = 580720
233 + 580487 = 580720

Showing the first eight; more decompositions exist.
