Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558280, here are decompositions:

29 + 558251 = 558280
71 + 558209 = 558280
83 + 558197 = 558280
101 + 558179 = 558280
113 + 558167 = 558280
131 + 558149 = 558280
167 + 558113 = 558280
197 + 558083 = 558280

Showing the first eight; more decompositions exist.
