Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558390, here are decompositions:

47 + 558343 = 558390
71 + 558319 = 558390
83 + 558307 = 558390
101 + 558289 = 558390
103 + 558287 = 558390
137 + 558253 = 558390
139 + 558251 = 558390
149 + 558241 = 558390

Showing the first eight; more decompositions exist.
