Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580728, here are decompositions:

11 + 580717 = 580728
17 + 580711 = 580728
37 + 580691 = 580728
41 + 580687 = 580728
89 + 580639 = 580728
97 + 580631 = 580728
101 + 580627 = 580728
151 + 580577 = 580728

Showing the first eight; more decompositions exist.
