Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57666, here are decompositions:

13 + 57653 = 57666
17 + 57649 = 57666
29 + 57637 = 57666
73 + 57593 = 57666
79 + 57587 = 57666
107 + 57559 = 57666
109 + 57557 = 57666
137 + 57529 = 57666

Showing the first eight; more decompositions exist.
