Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558318, here are decompositions:

11 + 558307 = 558318
29 + 558289 = 558318
31 + 558287 = 558318
67 + 558251 = 558318
109 + 558209 = 558318
139 + 558179 = 558318
151 + 558167 = 558318
179 + 558139 = 558318

Showing the first eight; more decompositions exist.
