Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580428, here are decompositions:

11 + 580417 = 580428
19 + 580409 = 580428
47 + 580381 = 580428
67 + 580361 = 580428
71 + 580357 = 580428
89 + 580339 = 580428
97 + 580331 = 580428
127 + 580301 = 580428

Showing the first eight; more decompositions exist.
