Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558880, here are decompositions:

11 + 558869 = 558880
17 + 558863 = 558880
53 + 558827 = 558880
89 + 558791 = 558880
149 + 558731 = 558880
197 + 558683 = 558880
251 + 558629 = 558880
269 + 558611 = 558880

Showing the first eight; more decompositions exist.
