Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558508, here are decompositions:

11 + 558497 = 558508
17 + 558491 = 558508
29 + 558479 = 558508
107 + 558401 = 558508
257 + 558251 = 558508
311 + 558197 = 558508
359 + 558149 = 558508
479 + 558029 = 558508

Showing the first eight; more decompositions exist.
