Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558208, here are decompositions:

5 + 558203 = 558208
11 + 558197 = 558208
29 + 558179 = 558208
41 + 558167 = 558208
59 + 558149 = 558208
179 + 558029 = 558208
191 + 558017 = 558208
227 + 557981 = 558208

Showing the first eight; more decompositions exist.
