Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558920, here are decompositions:

7 + 558913 = 558920
127 + 558793 = 558920
139 + 558781 = 558920
151 + 558769 = 558920
163 + 558757 = 558920
199 + 558721 = 558920
277 + 558643 = 558920
337 + 558583 = 558920

Showing the first eight; more decompositions exist.
