Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558388, here are decompositions:

101 + 558287 = 558388
137 + 558251 = 558388
179 + 558209 = 558388
191 + 558197 = 558388
239 + 558149 = 558388
359 + 558029 = 558388
401 + 557987 = 558388
461 + 557927 = 558388

Showing the first eight; more decompositions exist.
