Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558442, here are decompositions:

11 + 558431 = 558442
29 + 558413 = 558442
41 + 558401 = 558442
191 + 558251 = 558442
233 + 558209 = 558442
239 + 558203 = 558442
263 + 558179 = 558442
293 + 558149 = 558442

Showing the first eight; more decompositions exist.
