Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580438, here are decompositions:

29 + 580409 = 580438
59 + 580379 = 580438
107 + 580331 = 580438
137 + 580301 = 580438
179 + 580259 = 580438
251 + 580187 = 580438
269 + 580169 = 580438
359 + 580079 = 580438

Showing the first eight; more decompositions exist.
