Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558530, here are decompositions:

31 + 558499 = 558530
61 + 558469 = 558530
73 + 558457 = 558530
103 + 558427 = 558530
109 + 558421 = 558530
211 + 558319 = 558530
223 + 558307 = 558530
241 + 558289 = 558530

Showing the first eight; more decompositions exist.
