Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66724, here are decompositions:

3 + 66721 = 66724
11 + 66713 = 66724
23 + 66701 = 66724
41 + 66683 = 66724
71 + 66653 = 66724
107 + 66617 = 66724
131 + 66593 = 66724
137 + 66587 = 66724

Showing the first eight; more decompositions exist.
