Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558728, here are decompositions:

7 + 558721 = 558728
67 + 558661 = 558728
199 + 558529 = 558728
229 + 558499 = 558728
271 + 558457 = 558728
307 + 558421 = 558728
409 + 558319 = 558728
421 + 558307 = 558728

Showing the first eight; more decompositions exist.
