Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558228, here are decompositions:

5 + 558223 = 558228
19 + 558209 = 558228
31 + 558197 = 558228
61 + 558167 = 558228
79 + 558149 = 558228
89 + 558139 = 558228
107 + 558121 = 558228
137 + 558091 = 558228

Showing the first eight; more decompositions exist.
