Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558238, here are decompositions:

29 + 558209 = 558238
41 + 558197 = 558238
59 + 558179 = 558238
71 + 558167 = 558238
89 + 558149 = 558238
251 + 557987 = 558238
257 + 557981 = 558238
311 + 557927 = 558238

Showing the first eight; more decompositions exist.
