Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558638, here are decompositions:

97 + 558541 = 558638
109 + 558529 = 558638
139 + 558499 = 558638
181 + 558457 = 558638
211 + 558427 = 558638
331 + 558307 = 558638
349 + 558289 = 558638
397 + 558241 = 558638

Showing the first eight; more decompositions exist.
