Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558216, here are decompositions:

7 + 558209 = 558216
13 + 558203 = 558216
19 + 558197 = 558216
37 + 558179 = 558216
67 + 558149 = 558216
103 + 558113 = 558216
107 + 558109 = 558216
149 + 558067 = 558216

Showing the first eight; more decompositions exist.
