Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580400, here are decompositions:

19 + 580381 = 580400
43 + 580357 = 580400
61 + 580339 = 580400
97 + 580303 = 580400
109 + 580291 = 580400
181 + 580219 = 580400
199 + 580201 = 580400
307 + 580093 = 580400

Showing the first eight; more decompositions exist.
