Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558806, here are decompositions:

13 + 558793 = 558806
19 + 558787 = 558806
37 + 558769 = 558806
103 + 558703 = 558806
163 + 558643 = 558806
223 + 558583 = 558806
277 + 558529 = 558806
307 + 558499 = 558806

Showing the first eight; more decompositions exist.
