Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580388, here are decompositions:

7 + 580381 = 580388
31 + 580357 = 580388
97 + 580291 = 580388
157 + 580231 = 580388
307 + 580081 = 580388
421 + 579967 = 580388
439 + 579949 = 580388
631 + 579757 = 580388

Showing the first eight; more decompositions exist.
