Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580828, here are decompositions:

41 + 580787 = 580828
71 + 580757 = 580828
137 + 580691 = 580828
197 + 580631 = 580828
251 + 580577 = 580828
419 + 580409 = 580828
449 + 580379 = 580828
467 + 580361 = 580828

Showing the first eight; more decompositions exist.
