Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558028, here are decompositions:

11 + 558017 = 558028
41 + 557987 = 558028
47 + 557981 = 558028
101 + 557927 = 558028
137 + 557891 = 558028
167 + 557861 = 558028
197 + 557831 = 558028
227 + 557801 = 558028

Showing the first eight; more decompositions exist.
