Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571228, here are decompositions:

5 + 571223 = 571228
17 + 571211 = 571228
29 + 571199 = 571228
71 + 571157 = 571228
179 + 571049 = 571228
191 + 571037 = 571228
197 + 571031 = 571228
227 + 571001 = 571228

Showing the first eight; more decompositions exist.
