Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558556, here are decompositions:

17 + 558539 = 558556
23 + 558533 = 558556
59 + 558497 = 558556
83 + 558473 = 558556
269 + 558287 = 558556
347 + 558209 = 558556
353 + 558203 = 558556
359 + 558197 = 558556

Showing the first eight; more decompositions exist.
