Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558220, here are decompositions:

11 + 558209 = 558220
17 + 558203 = 558220
23 + 558197 = 558220
41 + 558179 = 558220
53 + 558167 = 558220
71 + 558149 = 558220
107 + 558113 = 558220
137 + 558083 = 558220

Showing the first eight; more decompositions exist.
