Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558180, here are decompositions:

13 + 558167 = 558180
31 + 558149 = 558180
41 + 558139 = 558180
59 + 558121 = 558180
67 + 558113 = 558180
71 + 558109 = 558180
89 + 558091 = 558180
97 + 558083 = 558180

Showing the first eight; more decompositions exist.
