Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82558, here are decompositions:

29 + 82529 = 82558
59 + 82499 = 82558
71 + 82487 = 82558
89 + 82469 = 82558
101 + 82457 = 82558
137 + 82421 = 82558
197 + 82361 = 82558
251 + 82307 = 82558

Showing the first eight; more decompositions exist.
