Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66658, here are decompositions:

5 + 66653 = 66658
29 + 66629 = 66658
41 + 66617 = 66658
71 + 66587 = 66658
89 + 66569 = 66658
149 + 66509 = 66658
167 + 66491 = 66658
191 + 66467 = 66658

Showing the first eight; more decompositions exist.
