Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558478, here are decompositions:

5 + 558473 = 558478
47 + 558431 = 558478
191 + 558287 = 558478
227 + 558251 = 558478
269 + 558209 = 558478
281 + 558197 = 558478
311 + 558167 = 558478
449 + 558029 = 558478

Showing the first eight; more decompositions exist.
