Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558872, here are decompositions:

3 + 558869 = 558872
43 + 558829 = 558872
79 + 558793 = 558872
103 + 558769 = 558872
151 + 558721 = 558872
211 + 558661 = 558872
229 + 558643 = 558872
331 + 558541 = 558872

Showing the first eight; more decompositions exist.
