Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66558, here are decompositions:

5 + 66553 = 66558
17 + 66541 = 66558
29 + 66529 = 66558
59 + 66499 = 66558
67 + 66491 = 66558
101 + 66457 = 66558
109 + 66449 = 66558
127 + 66431 = 66558

Showing the first eight; more decompositions exist.
