Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558658, here are decompositions:

29 + 558629 = 558658
47 + 558611 = 558658
59 + 558599 = 558658
71 + 558587 = 558658
137 + 558521 = 558658
167 + 558491 = 558658
179 + 558479 = 558658
227 + 558431 = 558658

Showing the first eight; more decompositions exist.
