Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558538, here are decompositions:

5 + 558533 = 558538
17 + 558521 = 558538
41 + 558497 = 558538
47 + 558491 = 558538
59 + 558479 = 558538
107 + 558431 = 558538
137 + 558401 = 558538
251 + 558287 = 558538

Showing the first eight; more decompositions exist.
