Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558518, here are decompositions:

19 + 558499 = 558518
61 + 558457 = 558518
97 + 558421 = 558518
199 + 558319 = 558518
211 + 558307 = 558518
229 + 558289 = 558518
277 + 558241 = 558518
379 + 558139 = 558518

Showing the first eight; more decompositions exist.
