Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580780, here are decompositions:

17 + 580763 = 580780
23 + 580757 = 580780
47 + 580733 = 580780
89 + 580691 = 580780
107 + 580673 = 580780
149 + 580631 = 580780
173 + 580607 = 580780
227 + 580553 = 580780

Showing the first eight; more decompositions exist.
