Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558628, here are decompositions:

17 + 558611 = 558628
29 + 558599 = 558628
41 + 558587 = 558628
89 + 558539 = 558628
107 + 558521 = 558628
131 + 558497 = 558628
137 + 558491 = 558628
149 + 558479 = 558628

Showing the first eight; more decompositions exist.
